Trimethyl-((1Z,3E)-1-phenyl-penta-1,3-dienyloxy)-silane is a complex organic compound with the molecular formula C14H20OSi. It is characterized by a trimethylsilyl group (Si(CH3)3) attached to a phenyl-penta-1,3-dienyloxy moiety, which consists of a phenyl ring connected to a conjugated diene system. The compound exhibits a (1Z,3E) configuration, indicating the presence of a Z-double bond at the first carbon-carbon double bond and an E-double bond at the third carbon-carbon double bond. This specific arrangement of double bonds influences the molecule's reactivity and properties. Trimethyl-((1Z,3E)-1-phenyl-penta-1,3-dienyloxy)-silane is primarily used in organic synthesis as a protecting group for alcohols and as a reagent in various chemical transformations, taking advantage of its stability and the ability to form stable silyl ethers.

Check Digit Verification of cas no

The CAS Registry Mumber 87514-20-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,5,1 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 87514-20:
(7*8)+(6*7)+(5*5)+(4*1)+(3*4)+(2*2)+(1*0)=143
143 % 10 = 3
So 87514-20-3 is a valid CAS Registry Number.

AN EFFICIENT SYMTHESIS OF SILYL ENOL ETHERS FROM α,β-UNSATURATED ALDEHYDES AND KETONES

Iqbal, Javed,Khan, M. Amin

, p. 515 - 522 (2007/10/02)

α,β-Unsaturated aldehydes and ketones when reacted with NaBr-Me3SiCl-Et3N in DMF at ambient temperature, yield silyl dienol ethers in high yields.

α:γ RATIOS IN PHENYLTHIOMETHYLATION OF SILYL DIENOL ETHERS

Fleming, Ian,Iqbal, Javed

, p. 2913 - 2916 (2007/10/02)

We report α:γ ratios for the electrophilic attack of phenylthiomethyl chloride on all the possible 2- and 4-methylated 1-phenyl-1-trimethylsilyloxybutadienes (7a-7e); the methyl groups appear to reduce the proportion of attack taking place at the carbon atom carrying the methyl groups.
