Preparation method of 1,3-diphenyl-1,1,3,3-tetramethyl disiloxane

The invention discloses a preparation method of 1,3-diphenyl-1,1,3,3-tetramethyl disiloxane. The preparation method is characterized in that the Wurtz method or Grignard method is adopted, and 1,3-diphenyl-1,1,3,3-tetramethyl disiloxane is synthesized through disiloxane rectified from an organosilicon high-boiling component and a halogenated compound. According to the preparation method, market application and high-value utilization of the organosilicon high-boiling component are expanded, and a raw material basis can be further provided for preparation of organosilicon materials with special functions.

Allyldimethylsilyl triflate: a self-catalyzed silyl nucleophile

Allyldimethylsilyl triflate 2 may be prepared by a protiodesilylation reaction between diallyldimethylsilane and triflic acid.This compound possesses both a silyl-substituted carbon nucleophile and the Lewis acid necessary for activation of an electrophile.Upon exposure to an aromatic aldehyde (e.g., p-MeOC6H4CHO), the homoallylic alcohol 4 is formed in good yield.The synthetic advantages of the intramolecular Cope-type cyclization reactio are discussed.
