Structure and Reactivity in the Reaction of Diazoindanes and Diazoindanones with Triphenylphosphine : The Formation of Mono-, and Bisphosphazines and Hydrazone-Compounds
Dae-Dong Sung*, Dong-Hyo Kang, Zoon-Ha Ryu
The reactions of diazoindanes and diazoindanones with triphenylphosphine have been studied in acetonitrile. The diazoindanes and diazoindanones react with triphenylphosphazine. The reaction of 1,3-bis(diazo)indan-2-one with a tenfold excess of triphenylphosphine in dry acetonitrile gave the 1,3-bis(phosphazino)indan-2-one, however in acetonitrile containing below of 1% water, the 1,3-bis(hydrazono)indan-2-one was produced by hydrolysis. The phosphazine compound could be easily converted into bishydrazone by recrystallization, due to small amounts of water in the solvent. The reactivity of triphenylphosphine toward diazoindanes and diazoindanones depends on the structrue of the diazo compounds.
