原位生成的[（BINAP）（PMe 3）Pt][BF 4]（2）与苄醇在室温下反应，得到[（BINAP）（PMe 3）Pt-H][BF 4]和苯甲醛。这种反应性对比类似地连接的铂-烷基物质，其即使在升高的温度下对β-氢化物消除也是稳定的。氢化铂的质子分解导致容易被弱配位配体（丙酮、五氟苯甲腈）取代的物质。
In situ-generated [(BINAP)(PMe3)Pt][BF4](2) reacts with benzyl alcohol at RT to yield [(BINAP)(PMe3)Pt-H][BF4] and benzaldehyde. This reactivity contrasts similarly ligated platinum-alkyl species, which are stable to beta-hydride elimination even at elevated temperatures. Protonolysis of the platinum hydride leads to a species that is readily substituted by weakly coordinating ligands (acetone, pentafluorobenzonitrile).
