henylphosphoranes (prepared by the action of alkylidenetriphenylphosphoranes on iodomethylsilicon compounds, followed by deprotonation of the resulting β-silylalkyltriphenylphosphonium iodides) with aldehydes and ketones provide a useful route to allylic silicon compounds. The β-silyl Wittig reagents prepared and utilized in this study include Pha3P=CHCH2SiMe3, Ph3P=C(CH3)CH2,SiMe3, Ph3P=C(C6H5)CH2SiMe3
β-甲硅烷基烷基亚甲基三苯基phenyl膦与醛和酮的反应(通过烷基亚甲基三苯基膦对碘甲基硅化合物的作用制备,然后使所得的β-甲硅烷基烷基三苯基phosph碘化物去质子化)为制备烯丙基硅化合物提供了一条有用的途径。本研究中制备和使用的β-甲硅烷基Wittig试剂包括Pha 3 P = CHCH 2 SiMe 3,Ph 3 P = C(CH 3)CH 2,SiMe 3,Ph 3 P = C(C 6 H 5)CH 2 SiMe 3,Ph 3 P = CHCH 2 SiMe 2H,Ph 3 P = CHCH 2 SiMe 2 OSiMe 3和Ph 3 P = CHCH 2 SiMe-(OSiMe 3)2。
