Synthesis of 1-Alkylthiovinyl- and 1-Arylthiovinyl-phosphonium Salts and Their Use in the Formation of Cyclopentanes
The synthesis of 1-methylthiovinyltriphenyl- and 1-phenylthiovinyltriphenyl-phosphonium salts (1; R = SMe and R = SPh) by introduction of a methylene group α- to the phosphonium centre in Ph3P+-CH2SR is described.The scope and limitations of the method are indicated.The salts (1; R = SMe and R = SPh) are used in the formation of highly functionalised cyclopentanes via an intramolecular Wittig reaction.
