ChemInform Abstract: Reactions of Dimethylsilylene with Pinenes.

Abstract

ChemInform Abstract Photolysis of β-pinene (I) with dodecamethylhexasilane (II) followed by methanol (III) quenching gives the allylsilane (IV) and the methoxysilane (V). The intermediacy of the silirane (VI) is proposed. Photolysis of α-pinene (VII) and (II) yields (V) only.he reaction of the photolytically generated dimethylsilylene with β-pinene (I) can be used as a way to introduce electrophiles into the allylic position such as demonstrated by reactions of (IV) with Br2/pyridine, MCPBA/H2SO4, and AcCl/AlCl3 giving the products (VIII)-(XI).
