Reactivity of 1-alkynylplatinum(II) complexes towards trialkylboranes

1-Alkynylplatinum(II) complexes of the type cis-[(dppe)Pt(C≡C-R1)2] [4, R1 = Me (a), tBu (b), C(Me)=CH2 (c), Ph (d), SiMe3 (e)], cis-[(dmpe)Pt(C≡C-Me)2] (5a), cis-[(depe)Pt(C≡C-Ph)2] (6d), cis-[(Et3P)2Pt(nBu)(C≡C-R1)] [7, R1 = Me (a), Ph (d)] and trans-[(Et3P)2Pt((E)-2-pentenyl)(C≡C-Me)] (8a) react with trialkylboranes R3B [2, R = Me (a), Et (b), iPr (c)] by 1,1-organoboration. This involves cleavage of a Pt-C ≡ bond, and formation of an alkynylborate-like intermediate in which a positively charged platinum fragment is coordinated to the C≡C bond. In most cases, the alkenylplatinum complexes of the type 9-13, 28, 30 which result from 1,1-organoboration are not stable, and either η2-alkyne platinum(0) (15-21, 29) or η3-borylalkene platinum(0) complexes (22-27) or both are the next products. The proposed structures of all new platinum complexes in solution are based on 11B, 31P, 195Pt NMR data, and in some cases also on complete 13C NMR data sets.
