  Water Addition to Alkynes Promoted by a Dicationic Platinum(II) Complex

  摘要：

  Dicationic platinum alkyne complexes were generated in situ by substitution of ethylene in [Pt(PNP)(C2H4)]-(BF4)(2) (PNP = 2,6-bis(diphenylphosphinomethyl)pyridine) with alkynes at low temperature. The dicationic acetylene complex readily adds water to form the platina-acetaldehyde complex [Pt(PNP)(CH2CHO)BF4, which was analyzed by X-ray diffraction. H-1 and P-31 NMR. studies were performed to elucidate the mechanism of formation of [Pt(PNP)(CH2CHO)BF4. A reversible acid base equilibrium between the platina-acetaldehyde and the corresponding eta(2)-vinyl alcohol complex [Pt(PNP)(CH2= CHOH)](2+) was observed. The complexes with terminal alkynes (propyne and 1-hexyne) gave with water a mixture of Markovnikov and anti-Markovnikov addition products [Pt(PNP){CH2C(O)R-1}BF4 and [Pt(PNP){C(O)CH2R1}]BF4 (R-1 = Me, n-Bu) in a ratio of 1:4. However, with tert-butyl- and phenylacetylene C H bond activation occurred, yielding the sigma-alkynyl complexes [Pt(PNP)(C equivalent to CR2)BF4 (R-2 = t-Bu, Ph). Complexes with internal allcynes (RC)-C-3 equivalent to CR4 (R-3 = Me; R-4 = Me, n-Pr) react with water and form the corresponding beta-ketonyl complexes [Pt(PNP){(CHRC)-C-3(O)R-4}]BF4. Moderate regioselectivity was observed for 2-hexyne.
