Oxidative coupling organometallic acetylides

The first method involves oxidative homo-coupling of bis (terminal alkynyl) complexes in the presence of a catalytic amount of a copper(I) halide and O2 as the oxidizing agent (Scheme 5.1, Eq. 5.1) [10]. The use of this catalyst system in organic synthesis is extensive and is better known as Hay s coupling reaction [11]. Extension of this methodology to organometallic synthesis was demonstrated by the conversion of trans-bis(acetylide) monomers into polymeric complexes. It is...
