摘要

Alkenyl (phenyl) iodonium tetrafluoroborates 3 were synthesized from alkenylsilanes 1 by the reaction with iodosylbenzene and boron trifluoride-diethyl ether or triethyloxonium tetrafluoroborate. The reaction proceeds stereospecifically with retention of configuration of 1. X-ray diffraction analysis of (4-tert-butylcyclohexenyl) phenyliodonium tetrafluoroborate (3b) revealed the highly ionic structure with the distorted T-shape arrangement. Iodonium ...
