The phenyl‐ and vinylrhodium(I) complexes trans ‐[Rh(R)(CO)(P i Pr 3 ) 2 ] ( 2, 3 ) were prepared from the chloro derivative 1 and Grignard reagents. The corresponding thiocar‐bonyl compound trans ‐[Rh(CH=CH 2 )(CS)(P i Pr 3 ) 2 ] ( 7 ) was obtained similarly from trans , ‐[RhCl(CS)(P i Pr 3 ) 2 ] ( 6 ) and CH 2 =CHMgBr. The preparation of 6 occurred via trans ‐ [RhCl(η 2 ‐ S=C= S)(P i Pr 3 ) 2 ] ( 5 ) as intermediate. The carbonyl complexes 2 and 3 are quite inert in the presence of CO and do not react by migratory insertion to give acylrhodium derivatives.
