Trineopentylphenylstannane, also known as tri(2-methylbutyl)phenylstannane, is an organotin compound with the chemical formula C19H34Sn. It is a colorless liquid at room temperature and is soluble in organic solvents. trineopentylphenylstannane is primarily used as a catalyst in various chemical reactions, such as the hydrostannation of alkenes and alkynes, as well as in the synthesis of organotin polymers. Trineopentylphenylstannane is also employed in the production of certain organotin stabilizers for PVC and as a reagent in the synthesis of other organotin compounds. Due to its potential environmental and health risks, proper handling and disposal procedures are essential when working with this chemical.

Check Digit Verification of cas no

The CAS Registry Mumber 34688-65-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,6,8 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 34688-65:
(7*3)+(6*4)+(5*6)+(4*8)+(3*8)+(2*6)+(1*5)=148
148 % 10 = 8
So 34688-65-8 is a valid CAS Registry Number.

Mechanism and Unusual Fragmentation Selectivities of Aryltrialkylstannane Cation Radicals

Luo, Pu,Dinnocenzo, Joseph P.

, p. 9240 - 9246 (2015/09/28)

Aryltrialkylstannane cation radicals were generated and characterized by nanosecond transient absorption spectroscopy. Kinetics show the fragmentations of the stannane cation radicals occur by a bimolecular, nucleophile-assisted mechanism (SN2). Consistent with this hypothesis, steric effects on both the nucleophile and the stannane cation radicals were observed. Steady-state, preparative photooxidation experiments show that aryltrimethylstannane cation radicals have an unusual preference for loss of aryl radicals over methyl radicals and that the selectivity for aryl vs methyl radical loss is dependent on the identity of the nucleophile. The preference for loss of aryl radicals is rationalized by a hypothesis based on Bents rules.
