The kinetics of the reaction between (CH2)4CH2>(dppe)2> (dppe=Ph2PCH2CH2PPh2) and BPh4 to yield NH(CH2)4CH2 and BPh4 (RCN is the solvent; R=Me, Et, or Ph) has been studied.In general the mechanism of the reactions involves two parallel pathways.Initial rapid protonation of the hydrazido(2-)-ligand and attack of a solvent molecule at the metal yields the spectrophotometrically detected hydrazidium species, trans-(CH2)4CH2>(NCR) (dppe)2>+.This species can either undergo slow nitrogen-nitrogen cleavage or react via an acid-catalysed pathway involving trans-(CH2)4CH2>(NCR) (dppe)2>2+ to yield products.The factors influencing whether protonation of hydrazido(2-)-ligands results in amine formation (N-N bond cleavage) or hydrazine formation (M-N bond cleavage) are discussed.
