General Description
1,2-Dibromoethyltrimethylsilane is a chemical compound with the molecular formula C5H11Br2Si. It is a colorless liquid with a strong, pungent odor, and it is insoluble in water but soluble in organic solvents. 1,2-Dibromoethyltrimethylsilane is commonly used as a reagent for the preparation of vinylsilanes, which are important intermediates in organic synthesis. It can also be used as a crosslinking agent in the production of functionalized silicones and in the synthesis of other organosilicon compounds. 1,2-Dibromoethyltrimethylsilane is a hazardous substance and should be handled with care, as it is corrosive to skin and can cause severe eye and respiratory irritation. It is important to use proper safety precautions and equipment when working with this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 18146-08-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,1,4 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 18146-08:
(7*1)+(6*8)+(5*1)+(4*4)+(3*6)+(2*0)+(1*8)=102
102 % 10 = 2
So 18146-08-2 is a valid CAS Registry Number.

Thermal rearrangements of spiro[2.4]hepta-1,4,6-trienes
Billups,Saini, Rajesh K.,Litosh, Vladislav A.,Alemany, Lawrence B.,Wilson, William K.,Wiberg, Kenneth B.

Thermolysis of spiro[2.4]hepta-1,4,6-triene (1a) at 50°C yielded bicyclo[3.2.0]hepta-1,3,6-triene (5), which dimerized in two different fashions to form cyclobutanes. The 1,2-dimethyl and 1-propyl derivatives of la also rearranged at 50°C, but at a faster rate, each yielding a pair of cyclobutane dimers. The structures of these symmetrical dimers were investigated by 1D and 2D NMR and NOE difference spectroscopy. Ab initio calculations indicated that the two strained olefins la and 5 had comparable energies about 50 kcal/mol lower than norborna-1(7),2,5-triene, which was thus excluded as a reaction intermediate.
