Synthesis of new mer,trans-rhodium(III) hydrido-bis(acetylide) complexes: Structure of mer,trans-[(PMe3)3Rh(CC–C6H4-4-NMe2)2H]
摘要:
Terminal alkynes (R-C C-H, R = 1-naphthyl, 9-anthryl, 4-Me2N-C6H4-, or the longer analogue, 4-(4-Me2N-C6H4 C C-)-C6H4) react with [Rh(PMe3)(4)Me] at ambient temperature, with loss of methane and one PMe3 ligand, to form the corresponding mer, trans-[(PMe3)(3)Rh(C CR)(2)H] compounds in excellent yield. In this preliminary study, the synthesis and spectroscopic characterization of the four new compounds are reported, along with the single-crystal structure of the R = 4-Me2N-C6H4 derivative.
