This thesis will discuss the synthesis of [Re6Q8]2+ (Q = Se or S) clusters containing N-heterocyclic carbenes (NHCs) as well as the use of silver(I)-IMes
(IMes = 1,3-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene) transmetalation reagents. The compound [Re6S8(PEt3)2(IMes)2Cl2] (PEt3 = triethylphosphine) has been isolated and fully characterized. Reactivity studies on [Re6S8(PEt3)2(IMes)2Cl2] have also been conducted with evidence of acetonitrile for chloride substitution. Additionally, syntheses of [Re6Q8]2+ containing NHCs without tertiary phosphines by using microwaves and
UV- light will be explored.
