A series of zinc dihalides [(IMes)ZnX2] [X = Cl (1a) Br (1b), I (1c); IMes = 1,3-bis(2,4,6-trimethylphenyl)imidazolin-2-ylidene] is reported. The iodide 1c underwent salt metathesis with NaH as an alternative synthesis of [(IMes)ZnH2]2 (2). 2 readily reacted with (tBu)NCO and Ph2CO under Zn-H insertion to give [(IMes)Zn(tBuNCHO-κN)2] (3) and [(IMes)Zn(OCHPh2)2] (4), respectively. Ph2S2 and I2 oxidized the hydride ligands in 2 to give dihydrogen and [(IMes)Zn(SPh)2] (5) and 1c, respectively. A series of mixed halo hydrides [(IMes)Zn(X)(H)]2 [X = Cl (6a), Br (6b), I (6c)] was obtained upon comproportionating 2 with 1ac. The new compounds were fully characterized, including X-ray crystallographic analysis of 3 and 6b.
