The latter reacts with dimethyl acetylenedicarboxylate (DMAD) to afford [Rh(μ-CS)(μ-DMAD)Cl2(dppm)2]. This complex is also formed from [Rh(μ-C)(μ-DMAD)Cl2(dppm)2] and sulfur. These strategies also afford the first rhodium selenocarbonyl complexes [Rh(μ-CSe)Cl2(dppm)2] and [Rh(μ-CSe)(μ-DMAD)Cl2(dppm)2].DP170102695 and DP190100723application/pdfen-AU© 2020 Royal Society of Chemistry2020-10-2510.1039/d0cc05106c
