Iodotripropylstannane, also known as Tripropyltin Iodide (TPTI), is an organotin compound with the chemical formula C9H21SnI. It is a colorless liquid at room temperature and is soluble in organic solvents. Iodotripropylstannane is primarily used as a precursor in the synthesis of other organotin compounds, which have applications in various fields such as agriculture, as biocides in antifouling paints, and in the production of heat-stable polymers. Due to its potential environmental and health risks, the use of organotin compounds like iodotripropylstannane has been restricted or banned in many countries.

7342-45-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7342-45-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,4 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7342-45:
(6*7)+(5*3)+(4*4)+(3*2)+(2*4)+(1*5)=92
92 % 10 = 2
So 7342-45-2 is a valid CAS Registry Number.

SUBSTITUTION AT SATURATED CARBON. PART 25. THE IODODEMETALLATION OF BENZYLTRIALKYLTINS IN METHANOL

Abraham, Michael H.,Andonian-Haftvan, Jenik

, p. 819 - 830 (2007/10/02)

The action of I2/I- in methanol on compounds PhCH2SnR3 leads only to cleavage of the benzyl group (as PhCH2I) when R=Et, Prn or Bun.With PhCH2SnMe3, both benzyl and methyl groups are removed.Rate constants are reported for the iododemetallation of all four PhCH2SnR3 compounds, R=Me, Et, Prn and Bun.The present results and previous literature data show that with a constant SnR3 leaving group, the sequence of alkyl-tin reactivity is Ph>PhCH2>Me>Et>Prn, with the benzyl-tin bond being broken 3-4 times as rapidly as the methyl-tin bond and about 40 times as rapidly as the ethyl-tin bond.The effect of added anions, Cl-, Br-, I- and ClO4- on the rate constants (and products) are reported, and it is shown that both kinetic studies and product analyses lead to the conclusion that foreign anions do not participate in the reaction mechanism.These are, however, specific kinetic salt effects in the order NaBrNaClNaClO4NaI.
