The + fragment amine, N(CH2CH2PPh2)3> readily reacts with NaSCH3 and LiSeCH3 yielding the methylchalcogenide derivatives (X = S, 1, Se, 2); the complexes have a trigonal-bipyramidal geometry with the P atoms of the np3 polydentate ligand in the equatorial plane and with the np3 nitrogen atom and the chalcogen atom in the axial positions. The chalcogen atom in these compounds is attacked by the electrophilic reagents CF3SO3CH3 and BF4 to yield the stable symmetrical and nonsymmetric dialkylchalcogenide complexes Y (R = CH3, Y = CF3SO3, X = S, 3, Se, 4, R = CH2CH3, Y = BPh4, X = S, 5, Se, 6). The ethyl methyl chalcogenide compounds 5 and 6 exhibit dynamic behaviour arising from inversion of configuration at the chalcogen atom. All dialkylchalcogenide complexes 3-6 react with CF3SO3H to yield the rare hydride dialkylchalcogenide complexes Y2 (R = CH3, Y = CF3SO3, X = S, 7, Se, 8, R = CH2CH3, Y = BPh4, X = S, 9, Se, 10).
