762-73-2 Usage
Description
Allyltrimethyltin, an organotin compound, is characterized by a tin atom connected to three methyl groups and one allyl group. It is recognized for its role in organic synthesis, specifically in the creation of carbon-carbon bonds. However, it is imperative to acknowledge its high toxicity, which poses severe health risks upon ingestion or inhalation. The environmental impact of allyltrimethyltin is also significant, as it is detrimental to aquatic life. Consequently, stringent regulations and safety protocols are essential for its handling and disposal to mitigate potential hazards.
Uses

Check Digit Verification of cas no
The CAS Registry Mumber 762-73-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,6 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 762-73:
(5*7)+(4*6)+(3*2)+(2*7)+(1*3)=82
82 % 10 = 2
So 762-73-2 is a valid CAS Registry Number.

Alkyl-substituted allylic lithium compounds: Structure and dynamic behavior
Fraenkel,Qiu
, p. 12806 - 12812 (2007/10/03)
Several methyl-substituted allylic lithium compounds have been prepared by CH3Li cleavage of their corresponding bis(methyl)bis(allylic)stannanes. Low-temperature 13C and proton NMR studies of 1:1 complexes of these allylic lithium compounds with TMEDA establish their structures. NMR line shape changes with temperature provide barriers to rotation. Results are listed in order as follows (allyl substituents, compound number, barrier to rotation in kcal·mol-1, and bonds undergoing rotation): 1,1-dimethyl, 26, 18, 2-3; endo-1-methyl, 27, 19, 2-3; endo-1-exo-3-dimethyl, 28, 21, 1-2 and 2-3. These observations together with the allylic 13C NMR chemical shifts indicate that in the case of unsymmetrical alkyl substitution at the termini the allyl C-C bond to the more substituted terminus is of higher bond order than that to the less substituted terminus. Unsymmetrical substitution is proposed to reduce the degree of delocalization compared to the symmetrically substituted allylic lithium compounds. A mechanism is proposed for the rotation process which is consistent with the Eyring activation parameters.
