Gold, 2,4-pentanedionato

Laser-induced decomposition of dimethyl(2,4-pentanedionato)goldm, 73, has been used426,427 recently for selective formation of high quality and high purity thin gold metallic films426 -428. An understanding of the mechanism of the thermal and photochemical decomposition of 73 is thus of scientific and practical interest. 

The isotopic studies of the mechanism of this reductive elimination process, involving breaking of M—C bonds followed by formation of C—C bonds, have been initiated by synthesis of (dimethyl-d6)(2,4-pentanedionato)gold, 73-(CD3)2, and identification of coupled reaction products produced in the pyrolytic decomposition carried out in sealed quartz NMR tubes in CD3OD and CV,Di2 solvents.
