Treatment of [Re 2 (CO) 8 (CH 3 CN) 2 ] with 2,7‐dipyridinyl‐1,8‐naphthyridine (bpnp) thermally provided mononuclear [( N , N′ ‐bpnp)Re(CO) 3 Cl] ( 1 ). Further reaction of 1 with rhenium carbonyls yielded ortho ‐metallation dinuclear rhenium complex 2 . Both complexes were characterized by spectroscopic analyses and single‐crystal X‐ray determination. Complex 1 also reacted with [PdMeCl(COD)] and [Ir(COD)Cl] 2 by means of ortho ‐metallation to yield the corresponding heterodinuclear species. Complex 2 appears to be an excellent precatalyst to promote the insertion of terminal alkynes into acetoacetates, which subsequently undergo cyclization to form 2‐pyranones.
