Abstract

Kinetic data are reported for ring opening of benzocyclobutene-1,2-dione, 3-phenylcyclobutene-1,2-dione, 4-methoxy-3-phenylcyclobutene-1,2-dione, and 3,4-dimethoxycyclobutene-1,2-dione with the zerovalent platinum complexes [Pt(trans-PhCHCHPh)(PPh3)2] and [Pt(PhCCPh)(PPh3)2]. Possible mechanisms, intramolecular in chloroform and dissociative in benzene, are proposed in the light of these results.

Abstract

The preparation of a series of 1-platinacyclopent-4-ene-2,3-dione complexes [[graphic omitted]Hv][L =AsPh3, PPh3, PEt2Ph, PEt3, PMePh2, PMe2Ph, P(OPh)3, Ph2PCH2CH2PPh2(dppe), pyridine (py), 2,2′-bipyridine (bipy), or 1,10-phenanthroiine (phen)] is described. Measurement of the coupling 2J(PtHv) between the vinylic proton. Hv, and platinum is expected to provide a measure of the trans influence of L. Instead an apparent trans-influence order AsPh3∼ PPh3 > P(OPh)3 > PMePh2 > PEt2Ph > PMe2Ph > PEt3 > dppe > py is indicated, more or less the reverse of what is expected. Determination of 1J(Pt13Cv) from 13C n.m.r. spectra of a selection of the complexes. however, has indicated the correct order. Phosphorus-31 n.m.r. spectra of the complexes L = PEt3, PMePh2 and PPh3 indicate that the COCO half of the chelate has a considerably lower trans influence than the vinylic half.
