Abstract
The reaction between copper(I) chloride and K[HB(pz)3](pz = pyrazol-1-yl) in the presence of CO affords white, crystalline [{HB(pz)3}Cu(CO)](I) as an air- and heat-stable copper carbonyl complex. Reactions between (I) and ligands L [L = PPh3, PMePh2, P(OMe)3, P(OPh)3, Ph2PCH2CH2PPh2(dppe), AsPh3, SbPh3, or ButNC] afford the complexes [{HB(pz)3}CuL]. On heating, (I) first decarbonylates to [Cu2{HB(pz)3}2](II) which then disproportionates to copper metal and Cu[HB(pz)3]2.Keywords
