✦ Synopsis
This new reaction should be applicable to other iodoalkynes. In this context, we have found that 1-( 1-cyclohexeny1)-2-iodoethyne (1 e) can also be dimerized by reaction with Ipy2BF4/HBF4 in CH,CI, (Scheme 3). Running the reaction n Q C Scheme 3. Synthesis of a cross-conjugated (dieny1)enyne by the head-to-tail coupling of an iodoenyne.
