In 1987 we published the first review on the magnetism of heteropoly-metallic systems (3). This article was largely devoted to the mechanism of the interaction in heterobinuclear complexes. The field of heteropoly-metallic compounds was covered up to the first attempts to obtain molecular-based magnets. The very last sentence of this article was One may anticipate that in a few years another review will be necessary, and that its main emphasis will be on systems of higher nuclearity and extended systems with subtle spin orders. In the present case, our prediction was quite correct, which is not so frequent in science. The field of heterobimetallic systems has developed tremendously since 1987, particularly in relation to the synthesis of molecular-based magnets. It is now timely to write a second review concerning this topic. 

The field of molecular-based magnets is obviously not limited to heterobimetallics. Great activity is devoted to compounds incorporating... 

Reed and White provided a rare example of an inter-molecular linear allylic C—H amination (LAA) using a heterobimetallic catalysts in which one of the catalysts was cobalt-based. " Treatment of allylcyclohexane 267 with A-(methoxycarbonyl)-p-toluenesulfonamide in the presence of commercially available catalysts bis-sulfoxide/Pd(OAc)2 and (salen)Co(III)OAc, benzoquinone (BQ) and tert-butyl methyl ether (TBME) gave the desired linear E-allylic amine 268 in 17% yield with...
