Hydroselenation and carboselenation of electron-deficient alkynes with isolable (Hydrido)(selenolato)platinum(II) complexes and a selenaplatinacycle bearing a triptycene skeleton

The reaction of [PtH(SeTrip) (PPh3)2] (Trip = 9-triptycyl) (3) with dimethyl acetylenedicarboxylate (DMAD) or methyl propiolate gave hydroselenation syn adducts. The reaction of [PtH(SeTrip)(dppe)J [dppe = 1,2-bis(diphenylphosphanyl)ethane], which has a stronger phosphane σ-donor ligand than 3, with DMAD gave both syn and anti adducts. The reaction of 3 and DMAD in the presence of PPh3 yielded no adducts. These observations indicate that, in the hydroselenation, the dissociation of a PPh3 ligand from 3 is a key step. The selenaplatinacycle 6, which is a thermal reaction product of 3, reacted with DMAD to give the carboselenation product, 1H-2-benzoselenin 7, which was also formed by the reaction of TripSeH with DMAD.
