P. Binger et al., DIMERIC BIS(TRIALKYLPHOSPHANE)RHODIUM CHL ORIDES - PREPARATION AND CHARACTERIZATION, Chemische Berichte, 127(10), 1994, pp. 1927-1929
High-yield methods for the preparation of (PMe3)3RhCl (2) and [(R3P)2R
hCl]2 [R = Me (3a); iPr (3b), and cyclohexyl (3c)] are described. The
dimeric nature of 3b in the solid state has been established by an X-r
ay analysis.
