文摘
The title compound has been prepared from bis[dichloro(η6-arene)ruthenium] (η6-arene = 1,2,3,4-C6Me4H2 (1a), p-cymene (1b) and tris(2,6-dimethoxyphenyl)phosphine (TDMPP). The crystal structure features a type of η3-phosphino-two phenoxides coordination. Reactions with its related phosphines, bis(2,6-dimethoxyphenyl)phenylphosphine (BDMPP) and (2,6-dimethoxyphenyl)diphenylphosphine (MDMPP) gave complexes with η2-phosphino-phenoxide and η1-phosphino coordinations, andtrans -RuCl2(MDMPP)2, depending on phosphines and arene groups.
