| Abstract: | The reaction of bromophosphite (ArO)2PBr {(ArO)2P = CH2(6-tBu-4-Me-C6H2O)2P} with lithium salt of 1,2-diphenylhydrazine gave phosphitohydrazine (ArO)2P-NPh-NPhH (2) in 64% yield. The last one reacted with Co[N(SiMe3)2]2 to afford cobalt(II) iminophosphoranate (PhN  P(OAr)2-NPh-)2Co (3), which is the result of isomerisation of the phosphitohydrazide ligand in coordination sphere of divalent cobalt. |
