Metal acetoacetonates

Metal acetoacetonates have often been used in spray pyrolysis, as explained in 17.3.8.5.3, but advances in sol-gel proeessing have tended to reduce the importance of this method. 

Other exploratory studies on the rearrangement of 3-aryl- and 3-(thienyl)-anthranils to acridones and thienoquinolones, (e.g., 140), respectively, indicate that these processes are catalyzed by transition metals (particularly iron powder), by various metal acetoacetonate complexes, and by group 6 metal carbonyls. In fact, by a judicious choice of catalyst the anthranils can be made to yield either o-aminoketones or acridones as the major thermolysis products.132...
