Halogen photoreductive elimination from gold(III) centers

Monomeric complexes of the type Au III (PR 3 )X 3 and bimetallic complexes of the type Au 2 I,III [μCH 2 (R 2 P) 2 ]X 4 and Au 2 III,III [μ-CH 2 (R 2 P) 2 ]X 6 (R = Ph, Cy, X = Cl - , Br - ) undergo facile photoelimination of halogen. M-X bond activation and halogen elimination is achieved upon LMCT excitation of solutions of Au III complexes in the presence of olefin chemical traps. As opposed to the typical one-electron redox transformations of LMCT photochemistry, the LMCT photochemistry of the Au III centers allows for theunprecedented (i) two-electron photoelimination of X 2 from a monomeric center and (ii) four-electron photoelimination of X 2 from a bimetalllic center. The quantum yields for X 2 photoproduction, in general, are between 10percent and 20percent for all species, showing only minimal dependence on the identity of the ligands about gold, or the nuclearity of the complex. Efficient X 2 photoelimination is observed in the absence of a chemical trap, providing a rare example of authentic, trap-free halogen elimination from a transitionmetal center.

C(3) aurated 1,4-benzodiazepin-2-ones. Synthesis and characterization. Crystal structure of (L)Au[P(C6H4CH3-4)3] (HL=7-chloro-1,3-dihydro-1-methyl-5-phenyl-2H-1,4-benzodiazepin-2-one, DIAZEPAM)

The synthesis of a series of gold(I) metallated derivatives of some 1,4-benzodiazepin-2-ones is described. They include mononuclear (L)Au(PR3) (R=C6H5, C6H4CH3-4 or C2H5) as well as dinuclear species (L)Au(Ph2P(CH2)nPPh2)Au(L), n=2, 3 (HL=7-chloro-1,3-dihydro-1-methyl-5-phenyl-2H-1,4-benzodiazepin-2-one, DIAZEPAM or 7-chloro-1-(cyclopropylmethyl)-1,3-dihydro-5-phenyl-2H-1,4-benzodiazepin-2-one, PRAZEPAM). The deprotonated ligand is bonded to the AuPR3 moiety through the C(3) atom. Activation of the C(sp3)-H bond is achieved by means of a strong base in the presence of the phosphinegold chloride intermediate. The structure of (L)Au[P(C6H5CH3-4)3] has been determined by X-ray diffraction. Some aspects of the reactivity of the metallated species is also reported.
