Temperature Solution

A new class of titanium complexes containing a tropidinyl (trop) ligand and a phosphinimido (R3P=N-) or a ketimide ligand (R2C=N-) were synthesized and characterized. The combination of the cyclopentadienyl equivalent tropidinyl and phosphinimido ligands enables the formation of a group of novel non-metallocene catalysts for olefin polymerization. The crystal structure of (trop)(t-Bu3PN)TiCl2 was determined by single crystal X-ray crystallography. Polymerization of ethylene with this complex was studied in a high-temperature solution process.Key words: tropidinyl, phosphinimido, ketimide, catalyst, polymerization.

The synthesis of RbHCN2 was carried out by reaction of cyanamide with rubidium amide in liquid ammonia. The crystal structure has been determinedo by x-ray powder methods (orthorhombic, P21,21,21, a = 7.299(1), b = 9.435(1), c = 9.420(1) Å; Z = 8). The anion is slightly bent (174°) and exhibits two different bond lengths (C-N: 1.17, HN-C: 1.31 Å).
