Cooperative B–H activation by Cp* based κ2-N,S-chelated Ru(ii) and Mo(ii) complexes (Cp* = η5-C5Me5)

Abstract

The chemistry of the Cp* based κ2-N,S-chelated ruthenium complex, [Cp*RuPPh32-N,S-(NC7H4S2)], 1 with different boranes has been explored. The room temperature reaction of 1 with BH3·THF and bulky boranes, such as MesBH2 and H2BArF, led to the formation of different dihydridoborate complexes, [{κ3-S,H,H-(NBH2R)(S2H4C7)}RuCp*], 2–4 (2: R = H, 3: R = Mes, and 4: R = ArF; Mes = 2,4,6-trimethylphenyl, and ArF = 3,5-bistrifluoromethyl-benzene). In contrast, the Cp* based κ2-N,S-chelated molybdenum complex, [Cp*Mo(CO)22-N,S-(NC7H4S2)}], 5, yielded the agostic borate species, [Cp*Mo(CO)22-S,H-(NBH2R) (NC7H4S2)}], 6 and 7 (6: R = Mes and 7: R = ArF) at elevated temperatures.
