An uncommon synergism in the concerted action of OH- and PR3 toward the simple Ru(II) complex Ru(CO)3Cl2(thf) allows a highly efficient reduction of the metal in ethanol or acetonitrile solution at 0 °C, with selective production of the corresponding Roper's-type Ru(0) complexes Ru(CO)2(PR3)3 in high yields within 10 min.

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].
Reactions of ruthenium(o) phosphine complexes with diphenylacetylene

, p. 5729 - 5736 (2008/10/09)
Heating diphenylacetylene with [Ru(CO)2(PPh3) 3] in toluene under reflux provides the 2-phenylindenone complex [Ru(η3=CCPh=CHC6H4)(CO)(PPh 3)2], arising from C-H activ
