Abstract

  • Several unexpected reactions have led to syntheses of cis-[Mo(CO) ((PPh ) -E)] in which E = O, S, NH. The E = O complex was obtained from the reactions of several acid chlorides (CH C(O)Cl, PCl , (MeO)P(O)Cl and [Mo(CO) -(PMe Cl)]) with [Et NH] cis-[Mo(CO) ((PPh O) H)] . The E = NH analog arose from the reaction of BF · O(C H ) with cis-[Mo(CO) (PPh NH ) ] and the E = S complex resulted from the reaction of H S with cis-[Mo(CO) (PPh -Cl) ]. The unsymmetrically substituted complex cis-[Mo(CO) (PPh OH)-(PPh OCH CH )] was obtained from the reaction of cis-[Mo(CO) (PPh Cl) ] with excess sodium ethoxide in ethanol. Cleavage of a PS bond in cis-[Mo-(CO) ((PPh ) S] with NaOH in the presence of Et N Cl yielded the unsymmetrical complex [Et N] cis-[Mo(CO) ((PPh O)(PPh S)H)] . Synthesis of cis-[Mo(CO) ((PPh O) P(O)CH Cl)] was accomplished by reacting (ClCH )-P(O)(OH) with cis-[Mo(CO) (PPh Cl) ]. Multinuclear NMR ( H, C, O, P) and IR spectroscopy assisted in complex characterization. Conductance measurements on acetone solutions proved the complexes [Et NH] cis-[Mo(CO) -((PPh O) E)] , where E = H , BF , and [Et N] cis-[Mo(CO) ((PPh O)-(PPh Y)H)] , where Y = O, S, to be 1/1 electrolytes. © 1982. 4 2 2 3 3 2 5 2 3 4 2 2 3 2 5 2 4 2 2 2 2 4 2 2 4 2 2 2 3 4 2 2 4 2 2 4 4 4 2 2 4 2 2 2 2 2 4 2 2 3 4 2 2 2 4 4 2 2 + - + - + - 1 13 17 31 + - + + + -
