1002-53-5 Usage

Description

Di-n-butyltin, a member of the organotin group, is a chemical compound synthesized from the reaction of butyltin trichloride with butyltin hydride. It is known for its diverse industrial applications, although its use has been associated with environmental and health concerns, particularly its toxic effects on marine life and potential as an endocrine disruptor.

Uses

Used in Plastics Industry:
Di-n-butyltin is used as a stabilizer in PVC products to prevent degradation and extend the lifespan of the materials.
Used in Chemical Industry:
Di-n-butyltin serves as a catalyst in the production of silicone rubbers, enhancing the efficiency and quality of the manufacturing process.
Used in Marine Coatings:
As a biocide, di-n-butyltin is used in antifouling paints to prevent the growth of marine organisms on ship hulls and other submerged structures, thereby reducing drag and improving fuel efficiency.
However, due to the environmental and health concerns associated with di-n-butyltin, its use has been regulated in many countries, and there is ongoing research into developing safer alternatives for its various applications.

Check Digit Verification of cas no

The CAS Registry Mumber 1002-53-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,0 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1002-53:
(6*1)+(5*0)+(4*0)+(3*2)+(2*5)+(1*3)=25
25 % 10 = 5
So 1002-53-5 is a valid CAS Registry Number.

Alternating polystannanes: Syntheses and properties

Harrypersad, Shane,Foucher, Daniel

, p. 7120 - 7123 (2015)

A new condensation polymerization route leading to alternating polystannanes is presented. The stoichiometric reaction of tin dihydrides and tin diamides in diethyl ether or toluene under mild reaction conditions afforded three new moderate molecular weig

Metal-Catalyzed Dehydropolymerization of Secondary Stannanes to High Molecular Weight Polystannanes

Imori, Toru,Lu, Victor,Cai, Hui,Tilley, T. Don

, p. 9931 - 9940 (1995)

The first high molecular weight polystannanes, H(SnR2)nH (R = nBu, nHex, nOct), result from dehydropolymerization of secondary stannanes R2SnH2 by zirconocene catalysts.Good catalysts include zirconocenes based on both CpCp*Zr (Cp* = η5-C5Me5) and Cp2Zr fragments, and the most active catalyst with respect to production of high molecular weight polystannanes was Me2C(η5-C5H4)2ZrMe.The latter catalyst produced H(SnnBu2)nH chains (Mw/Mn = 66 900/20 300) that were contaminated by ca. 18percent (by weight) low molecular weight cyclic oligomers.Lower molecular weights resulted from dehydropolymerizations of Me2SnH2, PhMeSnH2, and Ph2SnH2.At room temperature, H(SnR2)nH (R = alkyl group) polystannanes have λmax values at ca. 380-400 nm, attributed to ? --> ?* transitions.Thermal gravimetric analyses on the polystannanes reveal that these polymers are as thermally stable as related poly(dialkylsilane)s and have onset temperatures for thermal decomposition in the range 200-270 deg C, under both nitrogen and air.The H(SnnBu2)nH polymer has been shown to be a good precursor to SnO2, as shown by bulk pyrolysis in air (ceramic yield: 56percent).Preliminary results also indicate that these polymers may be useful as precursors to elemental tin.The polystannanes are photosensitive, and their photobleaching behavior has been characterized by UV-vis spectrometry and 119Sn NMR spectroscopy, which demonstrated that H(SnnBu2)nH is photochemically depolymerized to a 2:1 mixture of cyclo-(SnnBu2)5 and cyclo-(SnnBu2)6.The polymers H(SnnHex2)nH and H(SnnOct2)nH exhibit thermochromic behavior which is visibly evident as a discoloration from yellow to colorless upon warming above room temperature.This reversible behavior is associated with an abrupt change in λmax (e.g., from 402 to 378 nm for films of H(SnnOct2)nH) and a phase change at ca. 40 deg C (by differential scanning calorimetry).Thin films of H(SnnBu2)nH and H(SnnOct2)nH on glass slides were doped by exposure to SbF5 vapor to conductivities of 10-2 and 0.3 S cm-1, respectively.Preliminary experiments suggest that the dehydropolymerization occurs by a ?-bond metathesis mechanism involving four-center transition states.A previous report on production of high molecular weight poly(dibutylstannane) by the reductive coupling of nBu2SnCl2 by Na/15-crown-5 was reinvestigated and found to produce only low molecular weight material with Mw/Mn = 2400/1200.

Transition-Metal-Free Coupling Reaction of Vinylcyclopropanes with Aldehydes Catalyzed by Tin Hydride

Ieki, Ryosuke,Kani, Yuria,Tsunoi, Shinji,Shibata, Ikuya

, p. 6295 - 6300 (2015)

Donor-acceptor cyclopropanes are useful building blocks for catalytic cycloaddition reactions with a range of electrophiles to give various cyclic products. In contrast, relatively few methods are available for the synthesis of homoallylic alcohols through coupling of vinylcyclopropanes (VCPs) with aldehydes, even with transition-metal catalysts. Here, we report that the hydrostannation of vinylcyclopropanes (VCPs) was effectively promoted by dibutyliodotin hydride (Bu2SnIH). The resultant allylic tin compounds reacted easily with aldehydes. Furthermore, the use of Bu2SnIH was effectively catalytic in the presence of hydrosilane as a hydride source, which established a coupling reaction of VCPs with aldehydes for the synthesis of homoallylic alcohols without the use of transition-metal catalysts. In contrast to conventional catalytic reactions of VCPs, the presented method allowed the use of several VCPs in addition to conventional donor-acceptor cyclopropanes.

A convenient route to distannanes, oligostannanes, and polystannanes

Khan, Aman,Gossage, Robert A.,Foucher, Daniel A.

, p. 1046 - 1052 (2010)

The quantitative conversion of the tertiary stannane (ν;-Bu) 3SnH (2) into (ν-Bu)6Sn2 (4) was achieved by heating the neat hydride material under low pressure or under closed inert atmosphere conditions. A 31% conversion of Ph3SnH (3)to Ph6Sn 2 (5) was also observed under low pressure; however, under closed inert atmosphere conditions afforded Ph4Sn (6) as the major product. A mixed distannane, (ν-Bu)3SnSnPh3 (7), can also be prepared in good yield utilizing an equal molar ratio of 2 and 3 and the same reaction conditions used to prepare 4. This solvent-free, catalyst-free route to distannanes was extended to a secondary stannane, (ν-Bu)2SnH 2 (8), which yielded evidence (NMR) for hydride terminated distannane H(ν-Bu)2SnSn(ν-Bu)2H(9), the polystannane [(ν-Bu)2Sn] ' (10), and various cyclic stannanes [(ν- Bu)2Sn]ν=5,6=5,6 (11, 12). Further evidence for 10 was afforded by gel permeation chromatography (GPC) where a broad, moderate molecular weight, but highly dispersed polymer, was obtained (Mw = 1.8 × 104 Da, polydispersity index (PDI) = 6.9) and a characteristic UV-vis absorbance (1max)of ν370 nm observed.
