Reaction of methylthio-, ethylthio-, and benzylthiodiphenylcyclopropenium salts with 2,4-pentanedione (3a) and ethyl acetoacetate (3b) yielded the cyclopentadienol derivatives (4) by ring expansion.One of the products 4a was shown to be 4-acetyl-5-hydroxy

Alkylthiodiphenylcyclopropenium ions reacted with 2,4-pentanedione or ethyl acetoacetate to give cyclopentadienol derivatives by ring expansion, while triphenylcyclopropenium perchlorate yielded substituted cyclopropenes.
