article a survey is given of novel results in the field of the chemistry of a-diimine complexes of some metal atoms of the main group, transition metal and post transition metal area. It is shown that a-diimines of the type RN=C(R’)(R”)C=NR (= R-DAB) and 2C&NC(R’)=NR (= R-Pyca) are very versatile with regards to both their coordinationchemistry and chemical reactivity when coordinated to a metal or metal

Reversed-phase high performance liquid chromatography has been used to monitor the reactions of Ru3(CO)12 with 1,4-diazabutadiene (DAB) and of Ru2(CO)6 (DAB) with DAB. The kinetic data show that the formation of an intermediate in the former reaction is the rate determining step, which is first order in Ru3(CO)12 as well as in DAB. The reactivity depends strongly on the type of substituent on DAB.
