Methods for the Synthesis of the Diels−Alder Catalysts (ArO)2TiX2 (X = Cl, Br, I; Ar = 2-tert-Butyl-6-methylphenyl)
摘要:
A procedure for converting titanium diethylamidos to the corresponding dihalides (Cl, Br, I) and a complementary method for converting titanium dichlorides into dibromides and diiodides are reported These methods were utilized to synthesize a family of homogeneous and polymer-supported Diels-Alder catalysts with the general formula (ArO)(2)TiX2 (X = Cl, Br, I; Ar =2-tert-butyl-6-methylphenyl).
