RhCl 3 ‐Mediated Coupling Reactions of tert ‐Butyl Acetylene
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 acety...
