15729-58-5 Usage

Uses

Different sources of media describe the Uses of 15729-58-5 differently. You can refer to the following data:
1. Diiodomethane-d2 (CAS# 15729-58-5) is a useful isotopically labeled research compound.
2. Used to prepare deuterated fulvene for retro-Diels-Alder studies.

Check Digit Verification of cas no

The CAS Registry Mumber 15729-58-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,7,2 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 15729-58:
(7*1)+(6*5)+(5*7)+(4*2)+(3*9)+(2*5)+(1*8)=125
125 % 10 = 5
So 15729-58-5 is a valid CAS Registry Number.

Photoproduct Characterization and Dynamics in the 248 nm Photlysis of CH3I Thin Films on Ag(111)

Coon, S. R.,Myli, K. B.,Grassian, V. H.

, p. 16416 - 16424 (1995)

The 248 nm photochemistry of methyl iodide thin films was studied using reflection absorption infrared spectroscopy (RAIRS), temperature programmed desorption (TPD), and time-of-flight quadrupole mass spectrometry (TOF-QMS).The formation of predominantly CH2I2 and CH4 and some C2H6, CH3CH2I, CHI3 and I2 photoproducts retained in the film was characterized by RAIRS and TPD.The integrated areas of the IR absorption bands for the two major photoproducts, CH2I2 and CH4, increase to a maximum and then decrease as photolysis of the film proceeds.A cross section for the loss of CH3I by 248 nm photolysis of the film was measured to be (1.0+/-0.1)E-19 cm2, approximately 1 order of magnitude lower than the gas-phase cross section.At all laser fluences used in this study, CH3, I, and CH3I were ejected into the gas phase.The CH3 TOF distribution showed the signature of the gas-phase CH3I photodissociation dynamics-two sharp peaks corresponding to the production of iodine atoms in the I(2P3/2) and I*(2P1/2) states.The TOF distributions of I and CH3I were fit by Maxwell-Boltzmann distributions corresponding to temperatures of 1400 and 1170 K, respectively.Three other species-CH4, I2 and CH2I2-were observed in TOF-QMS, but only at higher laser fluences.It was determined that the I2 and CH2I2 species are most likely fragments of a larger molecule, perhaps a cluster species, that photodesorbs as the film becomes enriched with photoproducts.The mechanism for CH4 photoejection appears to be of a different nature.The photochemistry of methyl iodide thin films can be understood in terms of a combination of photoproceses occuring in the film and at the film surface.

Iron(I) mediated activation of C-C and C-H bonds of cis- and trans-1-acetyl-2-methylcyclopropanes in the gas phase: Competition between ring cleavage and α-CC-bond insertion reactions

Schalley, Christoph A.,Schr?der, Detlef,Schwarz, Helmut

, p. 11089 - 11097 (2007/10/02)

Unimolecular and collision induced fragmentations of cis- and trans-1-acetyl-2-methylcyclopropanes, complexed to bare Fe+ cations, were examined by means of tandem mass spectrometry. Stereoselective isotopic labeling data as well as comparative studies with acylic isomers reveal that two reaction pathways are in competition with each other. On the one hand, dehydrogenation, loss of ethene, and loss of acetaldehyde proceed via a common intermediate which is formed via ring cleavage of 1-acetyl-2-methylcyclopropane/Fe+ to yield the corresponding 3-hexen-2-one/Fe+ complexes; these undergo subsequently CH- and CC-bond activation via the remote functionalization mechanism. These ring cleavages are associated with a complete loss of stereochemical features for the cis and trans isomers. In contrast, unimolecular decarbonylation occurs stereoselectively and is favored for the trans isomers; this is rationalized via a stereoselective formation of cis- and trans-η3-allyl complexes in the course of the electrocyclic ring-opening process. Furthermore, interconversion reactions, thermodynamic and kinetic aspects, and isotope effects of the CH- and CC-bond activation processes are discussed.

High-Field NMR Determination of Magnetic Susceptibility Tensors and Angular Correlation Factors of Halomethanes

Bothner-By, A. A.,Dadok, J.,Mishra, P. K.,Zijl, P. C. M. Van

, p. 4180 - 4184 (2007/10/02)

Quadropolar splittings in the high resolution deuteron spectra of deuterated haloforms (CX3(2)H, X=Cl, Br, I) and methylene halides (CX2H(2)H) have been measured at 14.35 T (93.5 MHz) and used to determine the anisotropy or asymmetry of their molecular magnetic susceptibility tensors.By combination with the known isotropic susceptibilities, the principal susceptibility tensors have been deduced and decomposed into bond susceptibility tensors.Neither the average susceptibilities nor the principal susceptibility tensor elements of the complete halomethane series follow Pascal's additivity rules.The phenomenon is tentatively attributed to a variable paramagnetic contribution perpendicular to the X-bond.Angular correlation Kirkwood g2 factors have been determined for CHCl3 and CHBr3 and are compared with available literature data.
