Synthesis of platinacyclopentadienes via organoboration of cis-platinum(II) acetylides
Abstract
Platinacyclopentadienes are obtained in high yield from the reaction between trialkylboranes R3B (R = Me, Et, Pri) and cis-1,2-bis(diphenylphosphino)ethanediethynylplatinum(II) as the result of two consecutive 1,1-organoboration reactions.
