Methyl rheniumpentacarbonyl

Methyl rheniumpentacarbonyl reacts with anthraquinone to give an orthometallated product (160) [Eq. (49)]. Reaction of methyl rheniumpen-... 

Methyl rheniumpentacarbonyl has been subjected to three tetrafluoro-boranation studies, all by Beck and co-workers (20,162,163). The first study (162) involved treating the tetrafluoroborate derivative (formed by reaction of [Re(CH3)(CO)5] with triphenylcarbenium tetrafluoroborate) with a variety of cr and v donors, L, forming the salts [Re(L)(CO)s] BF4 [Eq. (51)]. The second study involved the formation of binuclear rhenium compounds (20) [Eq. (52)]. The third study used the tetrafluoroboranation reactions as a route to a polynuclear rhenium compound (163) [Eq. (53)]. 

Reaction with germyllithiutn reagents can yield CO inserted products (92) [Eq. (54)]. Thus methyl rheniumpentacarbonyl reacts with germyl-lithium compounds to give anionic acyl complexes which can be isolated as tetraethylammonium salts or alkylated to give carbene complexes.
