The cationic solvento species trans-[Pt(Me) (PPh3)2(solv)] [BF4] (solv = CH2Cl2, Et2O) reacts with 1.5 equiv. of p-tolylacetylene in the presence of a 10-fold excess of the hydroxylated compounds HOCH2CH2X (X = Br, I, OH) to give the corresponding (alkoxy)alkyl carbene complexes frans-[Pt(Me) {=C(OCH2CH2X)CH2(p-tolyl)}(PPh 3)2] [BF4] (1-3). Complexes 1-3 were also obtained by reaction of the acetylide complex trans-[Pt(Me) (C≡CR) (PPh3)2] (R=p-tolyl) in the presence of 1 equiv. of HBF4 with an excess of HOCH2CH2X. The carbene complex trans-[Pt(Me) {=C(OCH2CH2Cl)CH2R}(PPh3) 2][BF4] (R = p-tolyl) can be readily deprotonated by NEt3 to afford the vinyl complex trans-[Pt(Me) {C(OCH2CH2Cl)=CH(R)}(PPh3)2] (4). A similar behavior is observed also for 1-3 when treated with a base.
