摘要

Allyl propynyl ethers of general formula RCECCHZOCHZCH= CHR (1) undergo cycloremangement to 3-oxabicyclo [4. l. 0lhept-4-enes (2) in oxygen-free benzene upon brief treatment at room temperature with catalytic amount of PtC14. The transformation of 1 to 2 is assumed to involve platinumallene intermediates. The structure of 7-(l-naphthyl)-6- phenyl-3-oxabicyclo [4. l. 0lhept-4-ene(2c) has been determined by X-ray diffraction ...
