  Autocatalytic Alkyne Cycloadditions:  Evidence for Colloidal Pt Catalysis

  摘要：

  Treatment of the four-membered platinacycle L2Pt(1,8-naphthalendiyl) (1) or the five-membered platinacycle L2Pt(1,12-triphenylendiyl) with excess PhCCPh at 120-150 degrees C gives the coupling products 1,2-diphenylacenaphthalene or 4,5-diphenylbenzo[e]pyrene and the alkyne complex L2Pt(eta2-PhCCPh). Both reactions show an accelerating rate, which has been traced to catalysis of the reaction by colloidal platinum formed by the reaction of O2 with L2Pt(eta2-PhCCPh).

  Bromination of a Naphthalene Platinacycle

  摘要：

  Bromination of the four-membered Pt(II) metallacycle Pt(Et3P)(2)(1,8-naphthalendiyl) by Br-2 results in Pt-C bond cleavage and formation of cis-Pt(8-bromonaphthalen-1-yl)(Br)(PEt3)(2) (cis-2). Further Br-2 addition yields ionic cis-[Pt(eta(2)-8-bromonaphthalen-1-yl)(Br)(2)(PEt3)(2)]Br (cis-3) in which the bromine atom of the bromonaphthalene is bonded to the six-coordinate Pt(IV) center. AgPF6 and cis-3 give AgBr and cis-[Pt(eta(2)-8-bromonaphthalen-1-yl)(Br)(2)(PEt3)(2)]PF6 (cis-4). All of the above complexes isomerize to more stable trans-complexes. Complex cis-3 slowly converts to neutral Pt(eta(2)-8-bromonaphthalen-1-yl)(Br)(3)(PEt3) (5) through displacement of a PEt3 ligand by Br-. Photolysis of 5 yields naphthalene, Pt2Br4(PEt3)(2), Et3PBr2, and other products. Na/Hg eduction of 5 gives trans-2 and other unidentified products.
