RhCl 3 is shown to mediate unusual coupling reactions of tert ‐butyl acetylene. When RhCl 3 (H 2 O) n was heated with four equivalents of tert ‐butyl acetylene in methanol, the dinuclear complex [{Rh(μ‐Cl)(CH 2 t Bu)( t BuC=CHCOCH 2 t Bu)} 2 ] ( 2 ) was isolated. A larger excess of tert ‐butyl acetylene (12 equiv.) resulted in the formation of the dimer [{η 5 ‐C 5 H 2 t Bu 2 (CH 2 t Bu)}Rh(μ‐Cl) 3 Rh(C 24 H 42 O 2 )] ( 3 ). Both complexes were analyzed by single‐crystal X‐ray diffraction.
