  Reactions of {TiO(salen)}n [salen=N,N′-bis(salicylidene)ethylenediamine] in aromatic aldehydes and ketones

  摘要：

  Polymeric {TiO(salen)}(n) prepared from {Ti(OCHMe2)(2)(acac)(2)} and salen-H-2 in MeOH and with an apparent chain structure, is mostly insoluble but dissolves when strongly heated in aromatic aldehydes or ketones, depositing the insoluble form again on cooling. p-Tolualdehyde performed differently, giving a red solution from which insoluble red crystals were deposited. X-ray crystallography showed the complex was [{Ti(salen)(O2CC6H4Me-4)-O-Ti(salen)(O2CC6H4Me-4)]. Solvent (1) (solvent = p-tolualdehyde or p-toluic acid) containing a Ti-O-Ti bridge. Reaction of (TiO(salen)), with p-tert-butylbenzoic acid in the presence of excess p-tolualdehyde gave [{Ti(salen)(O2CC6H4CMe3-4)-O-Ti(salen)(O2CC6H4CMe3-4)]. 4-CH3C6H4CHO (2) for which an X-ray crystal structure determination indicated similar connectivity around the metal as for (1). (TiO(salen)) heated strongly in isobutyrophenone (PhCOCHMe2) also gave red crystals which X-ray analysis showed structural similarity to (1) and (2) but incorporating a PhCO2-ligand. {TiO(salen)) heated in acetophenone gave a product which X-ray analysis showed was a dioxo-bridged dimer (4) in which C-C bond formation had occurred on one side of each salen ligand.
