Reversible CâN bond formation of a parent imido complex trans-Mo(NH)(OTf)(syn-Me8[16]aneS4)} OTf 1 proceeds through addition of acetone and benzaldehyde to give α-hydroxyalkylimido complexes trans-Mo[NC(OH)RRâ²](OTf)(syn-Me8[16]aneS4)}OTf (2; RRâ²Me, 3; RH, Râ²Ph); the structures of two imido complexes 1 and 3 as well as trans-Mo(N â BPh3)(OTf)(anti-Me8[16]aneS4)4 obtained by treating 1 and 2 with NaBPh4 were elucidated by X-ray diffraction study.
