Unexpected reaction of benzoates with chlorovinylsilanes in the presence of magnesium: A facile synthesis of (3-Oxo-3-phenyl)propylvinylsilanes and further transformations

Tongco, Emily C.,Wang, Qunje,Prakash, G.K. Surya

, p. 1081 - 1084 (2007/10/03)

(3-0xo-3-phenyl)propylvinylsilanes, new functionalized monomers, have been synthesized in modest to good yields, by the reaction of methyl benzoates with chlorodimethylvinylsilane in the presence of magnesium. The synthetic potential of these new compounds was investigated in siloxane synthesis and hydroxy transformation.
