Preparation and reactivity of hydrazine complexes of rhenium: Synthesis of 1,2-diazene (NH=NH) and methyleneimine (CH2=NH) derivatives

The hydrazine complexes [Re(RNHNH2)(CO)nP 5-n]BPh4 [R = H, CH3, Ar; n = 1-4; P = P(OEt)3, PPh(OEt)2, PPh2OEt] were prepared by allowing the hydride species [ReH(CO)nP5-n] to react first with a Bronsted acid and then with hydrazine. The reaction of either [Re(NH2NH2)(CO)nP5-n]BPh 4 or [Re(ArNHNH2)(CO)nP5-n]BPh 4 with Pb(OAC)4 at -40 °C proceeds with the selective oxidation of the hydrazine ligand to yield either [Re(NH=NH)(CO) nP5-n]BPh4 or [Re(ArN=NH)(CO)nP 5-n]BPh4. The oxidation of [Re-(CH3NHNH 2)(CO)nP5-n]BPh4 (n = 1, 2) with Pb(OAc)4 at -40 °C gives both [Re(CH3N=NH)(CO) nP5-n]BPh4 and [Re(η-NH=CH 2)(CO)nP5-n]BPh4. Reduction reactions of both hydrazine and diazene complexes with Zn amalgam were also studied and yielded ammonia in moderate yield (20-25%). ( Wiley-VCH Verlag GmbH & Co.
