Popis:	The reaction of titanium(IV) alkoxides in 1:1 stoichiometry with 2-methyl-2,4-pentanediol, pyrocatechol, salicylic acid, or P,P'-diphenylmethylenediphosphinic acid yields chelates of the form Ti(BB)(OR)2, where BB represents the binegative bidentate ligands involved and R ethyl or isopropyl. A similar reaction with 1,3-propanediol does not produce Ti(OC3H6O)(OR)2, but instead Ti(OC3H6O)2 and Ti(OR)4 are recovered. The Ti(BB) (OR)2 derivatives are all associated in solution. Replacement of the alkoxy groups with acetylacetonate groups in the pyrocatecholate derivative gives the monomeric mixed chelate (Ti(o-C6H4O2)(C5H7O2)2). P,P'-Diphenylmethylenediphosphinic acid was prepared via the reaction of diisopropyl phenylphosphonite with methylene iodide. (Author)
