55644-08-1 Usage
Uses
Used in the Chemical Industry:
Dimethyl-bis-(a-bromoisopropyl) Silane is used as an intermediate in the synthesis of various organosilane compounds for its ability to facilitate the formation of silicon-carbon bonds and its reactivity in specific chemical reactions.
Used in the Preparation of Hexamethylsilirane:
Dimethyl-bis-(a-bromoisopropyl) Silane is used as a precursor in the preparation of Hexamethylsilirane, a volatile and highly flammable organosilane compound. Its role in this process is crucial due to its compatibility with the reactants and its ability to undergo specific transformations to yield the desired product.
Check Digit Verification of cas no
The CAS Registry Mumber 55644-08-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,6,4 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 55644-08:
(7*5)+(6*5)+(5*6)+(4*4)+(3*4)+(2*0)+(1*8)=131
131 % 10 = 1
So 55644-08-1 is a valid CAS Registry Number.

HEXAMETHYLSILIRANE. I. PREPARATION, CHARACTERIZATION AND THERMAL DECOMPOSITION
Seyferth, Dietmar,Annarelli, Dennis C.,Vick, Steven C.,Duncan, Don P.

Hexamethylsilirane has been prepared by the action of magnesium on dimethyl-bis(α-bromoisopropyl)silane in tetrahydrofuran (THF) solution.It was found to be highly reactive toward atmospheric oxygen and moisture and to decompose when heated in solution at 60-75 deg C.Its decomposition results in the extrusion of dimethylsilylene which may add to the tetramethylethylene produced in the decomposition to regenerate the silirane, insert into the reactive SiC2 ring of the silirane to give octamethyl-1,2-disilacyclobutane or oligomerize to give (Me2Si)n oils.Dimethyldiisopropyl-, tetraisopropyl- and tert-butyltriisopropylsilane were prepared by catalytic hydrogenation of the corresponding isopropenylsilanes.Bromination of dimethyldiisopropylsilane at 65 deg C resulted in exclusive formation of dimethyl-bis(α-bromoisopropyl)silane.
