Terminal acetylenes react with cis-RuMe2(PMe3) 4 to form the bis(acetylido) complexes cis/trans-Ru(C=CR) 2(PMe3)4 in good yield. The structures of trans-2 (R = Ph), cis-3 (R = p-C6H4-OMe), trans-4 (R = p-C6H4-Me), cis-6 (R = Me), trans-7 (R = SiMe3) and cis-8 (R = H) were determined by X-ray crystallography. © 2008 Wiley-VCH Verlag GmbH & Co.
