Derivatives of titanium with compounds having bidentate ligands III. Reactions of titanium alkoxides with acetylacetone

The reactions of titanium alkoxides (methoxide, ethoxide and isopropoxide) with acetylacetone (Hacac) have been found to yield two types of derivatives: Ti(OR)3(acac) and Ti(OR)2(acac)2. Unsuccessful attempts have been made to prepare Ti(OR)(acac)3 by the reaction of Ti(OR)2(acac)2 and Ti(OR)4 with excess of the ligand, which yields a compound with composition TiO(acac)2. The titanyl derivative crystallised from dioxane with a molecule of dioxane of addition. A number of higher alkoxide derivatives with the formulae Ti(OR)3(acac) and Ti(OR)2(acac)2 have been synthesised by alcoholysis reaction of the corresponding methoxide, ethoxide and isopropoxide compounds
