  Enhanced C−C Bond Formation of Heterodinuclear Methylplatinum−Molybdenum Complexes Having a Hemilabile Ligand with Dialkyl Acetylenedicarboxylate

  摘要：

  Heterodinuclear methylplatinum-molybdenum complexes having a hemilabile P-L ligand, (P-L)MePt-MoCP(CO)(3) (P-L = Ph2PC2H4NEt2 (1), Ph2PC2H4CH=CH2 (2)), react with dialkyl acetylenedicarboxylate to afford the novel heterodinuclear complexes (P-L)MePt-{mu-eta(2):eta(2)-C(O)C-2(CO2R)(2)}MoCP(mu-CO)(CO) (P-L = Ph2PC2H4NEt2, R = Me (5); P-L = Ph2PC2H4CH=CH2, R = Me (6); P-L = Ph2PC2H4NEt2, R = Et (7)). An X-ray diffraction study of 5 has revealed that the complex has a unique structure containing a platinacyclobutenone framework, where the pi-bond coordinates to the molybdenum. Heating of 5 at 50 T for 2 days results in reductive elimination of methyl and alkenyl ligands followed by decarbon-ylation to form the new mu-alkenyl type complexes ((Ph2PC2H4NEt2-KN)-N-2,P), {mu-MeO2C(Me)=CCO2-Me}Pt-MoCp(mu-CO)(CO) (8) and ((Ph2PC2H4NEt2-KP)-P-1)(CO){mu-MeO2C(Me)=CCO2-Me}PtMoCp(mu-CO)(CO) (9). Reactions of 5 with (BuNC)-Bu-t or PMe3 cause selective ligand displacement of the amino moiety in the P-N ligand to form ((Ph2PC2H4NEt2-KP)-P-1)(L')MePt,{mu-eta(2):eta(2)-C(O)C-2(CO2Me)(2)}MoCP(U-CO)(CO) (L' = (BuNC)-Bu-t (10), PMe3 (11)). On the other hand, nucleophiles such as H2NBu, HNEt2, pyrrolidine, and KOPh add to acyl carbon to give the trisubstituted mu-alkenyl type complexes ((Ph2PC2H4NEt2-KN)-N-2,P)Me{mu-MeO2C(R2NCO)C= CCO2Me}Pt-MoCp(mu-CO)(CO) (NR2 = NHBu (12), NEt2 (13), NC4H8 (14)) and K+[((Ph2PC2H4NEt2-KP)-P-1)Me{mu-MeO2C(PhO2C)C=CCO2Me}Pt-MoCp(mu-CO)(CO)](-) (15).
