Abstract

Abstract The synthesis of unsymmetrical (Z)-1-alkyl-3-(2-iodovinyl)-2-phenyl-1- cyclopropenes (R= Me (8 a), Et (8 b), iPr (8 c), and tBu (8 d)) and their reactions with Vaska's complex [Ir (CO) Cl (PPh 3) 2] and its trimethylphosphine analogue [Ir (CO) Cl (PMe 3) 2] were investigated. Iridabenzvalene (13/20), iridabenzene (14/21), and/or η 5- cyclopentadienyliridium complexes (15/22) were obtained in modest yields and were fully ...
