The dialkylgermylene [Ge(CH[SiMe3]2)2] (3) converts the carbene complexes [Ru(CHR)(PCy3)2Cl 2] (R = p-C6H4Me [2], n-C4H 9 [6]) into the corresponding square-planar carbyne complexes [Ru(CR)(PCy3)2Cl] (R = p-C6H4Me [1], n-C4H9 [7]) cleanly within minutes at 25°C in benzene; addition of HCl to a benzene solution of 1 results in quantitative re-formation of 2. Replacement of chloride in 1 affords other halide and pseudohalide complexes, [Ru[C-p-C6H4Me)(PCy 3)2X] (X = p-OC6H4-t-Bu, Br, F, O3SCF3), cleanly.
