Description

General description

1,7-Octadiyne is a terminal bis-alkyne and participates in the formation of uranium(IV) vinyl complexes. It reacts with frustrated Lewis pair P(o-tolyl)3/B(C6F5)3 by acetylene C-C coupling to yield the zwitterionic product. It undergoes the reductive cyclization during reaction with Re2Cl4(μ-dppm)2 (dppm = Ph2PCH2PPh2) and affords quadruply bonded dirhenium(III) complex Re2Cl3(μ,η2-C8H7)(μ-dppm)2.
