Rhenium orthometallation

Compared to manganese, little work has been carried out on analogous alkyl complexes of rhenium, although that which has may be divided into the same categories, namely, (1) reaction with transition metal hydrides, for example [CpW(H)(CO>3] (2) reaction with Lewis acids, for example, AlCUEt (3) orthometallation reactions (4) reaction with cationic species, for example, (5) reaction with anionic nucleophiles, for example, BF4" (6) reaction with neutral nucleophiles, for example, PPh3-... 

Examples of the promotion of orthometallation by oxygen donors are limited to side chains containing ketonic and amide carbonyl groups. The use of ketone oxygen as the donor atom to promote orthometallation has been reported only for manganese and rhenium carbonyl derivatives ...
