Bis(alkynyl), metallacyclopentadiene, and diphenylbutadiyne complexes of ruthenium

Heating diphenylbutadiyne with [Ru(CO)2(PPh3) 3] or [Ru(CO)3(PPh3)2] in toluene under reflux provides respectively the ruthenacyclopentadiene [Ru{κ2-CR=CPhCPh=CR}(CO)2(PPh3) 2] (R = C≡CPh) or the cyclopentadienone complex [Ru{η4-O=CC4Ph2R2}(CO) 2(PPh3)], the latter via [2 + 2 + 1] alkyne and CO cyclization. The bis(alkynyl) complex cis,cis,trans-[Ru(C≡CPh) 2(CO)2(PPh3)2] is not formed in either of these reactions but is the product of the reaction of [RuCl 2(CO)2(PPh3)2] with LiC≡CPh or of cis,-mer-[Ru(C≡CPh)2(CO)(PPh3)3] with CO. Although the bis(alkynyl) complex does not undergo reductive elimination to provide the diyne complex, thermolysis of cis,cis,trans-[Ru(C≡CPh) (HgC≡CPh)(CO)2-(PPh3)2] (obtained from [Ru(CO)2(PPh3)3] and [Hg(C≡CPh) 2]) provides a noninterconvertible 1:1 mixture of cis,cis,trans-[Ru(C≡CPh)2(CO)2(PPh3) 2] and [Ru(η-PhC≡CC≡CPh)(CO)2(PPh 3)2].
