Study on the Reactions of the Dinitrogen Complexes trans- (M = Mo or W) with Ethyldiazoacetate: Formation of an Azo Compound and of a Phosphazene Species

Article abstract of DOI:10.1007/BF00810890

Complex trans- (dppe = Ph2PCH2CH2PPh2) reacts with NN = CHCOOEt in benzene solution to afford benzene-azomethane, Ph-N=N-CH3, as the main organic product.However, the phosphazene species Ph2P(N2CHCOOEt)(CH2CH2)P(N2CHCOOEt)Ph2 is formed by irradiating a THF solution of trans- in the presence of ethyldiazoacetate; in moist solution, the phosphazene bonds undergo a partial hydrolysis, and the phosphonium species ²⁺ appears to be formed. - Keywords: Catalysis; Dinitrogen complexes; Ethyldiazoacetate
