Synthesis of aldehydes from phenylthiotrimethylsilylmethane
摘要:
Phenylthiotrimethylsilylmethyl-lithium (4) reacts with alkyl halides to give 1-phenylthio-1-trimethyl-silylalkanes (5), which can also be prepared by the addition of alkyl-lithium to 1-phenylthio-1-trimethylsilylethene (8), or from bis (phenylthio) acetals (11). The 1-phenylthio-1-trimethylsilylalkanes (5) can be converted into the corresponding aldehyde (15) by oxidation to the sulphoxide (13), thermal rearrangement, and hydrolysis of the resultant O-silyl thioacetal (14).
