Popis:	The systematic syntheses of some new electron-poor ReI(N2) complexes are described. The oxidation potentials of these complexes vary essentially linearly with ν(N2) whilst only those with E½ox > ca. +0.8 V versus the saturated calomel electrode react with LiMe. In general, the nature of the product(s) of reaction of these complexes with LiR (R = alkyl or aryl) depend upon R. For example, [ReCl(CO)2(N2)(PPh3)2] reacts with LiMe–H+ to give [ReCl{C(OH)Me}(CO)(N2)(PPh3)2], but with LiPh–H+ gives the five-co-ordinate [ReCl(CO)2(PPh3)2]. We have not observed attack by LiR upon N2 in any of the complexes. The apparent selectivity of the site of attack by LiR is discussed.
