- Synthesis of (NHC)Pd(salicylaldimine)Cl complexes through template-directed ortho-aromatic metaloxylation of NHC-palladacycles derived from arylimines
-
Reactions of imidazoliums with palladacycles afforded NHC-palladacycle complexes. The reactivity of the NHC-palladacycles was explored and the results demonstrated that they could be template-directed ortho-aromatic metaloxylated in the presence of tert-b

- Bis(salicylaldiminato)titanium complexes containing bulky imine substituents: Synthesis, characterization and ethene polymerization studies
-
A series of titanium complexes bearing two anionic [N, O-] bidentate salicylaldiminato ligands, namely bis[(N-salicylidene)anilinato]titanium(IV) dichloride (1), bis[(N-salicylidene)-2,6-dimethylamlinato]titanium(IV) dichloride (2), bis[(N-salicylidene)-2,6-di-i- propylanilinato]titanium(IV) dichloride (3), bis [(N-salicylidene) - (1-naphthalenylimino)]titanium(IV) dichloride (4), bis[(N-salicylidene)-2,6-difruoroanilinato]titanium(IV) dichloride (5), and bis[(N-3-fluorosalicylidene)-2,6-difluoroanilinato]titanium(IV) dichloride (6) have been synthesized with good yields by a two-step procedure. The X-ray structure analysis reveals that in complex 2, titanium has a distorted octahedral coordination sphere in which the oxygen atoms and the chloride ligands form the basal plane. Both the chloride and the phenoxy moieties have a cis orientation and the angle between the chloride ligands is 93.05°. The imine nitrogen atoms complete the octahedral coordination of the Ti center by occupying the axial positions. The newly synthesized (2 and 4-6) and already known complexes (1 and 3) were introduced in detailed ethene-polymerization studies. The activities achieved were low to moderate depending on the size and nature of the imino substituents. The polyethenes (PEs) produced had high molar masses, and the modalities of the molecular weight distributions varyied with polymerization temperature. Based on the results of ab initio calculations and on the experimental data obtained, an explanation for uni- and bimodal polymerization behavior and the differences in catalytic activities are given.

- METAL COMPLEXES FOR USE IN OLEFIN METATHESIS AND ATOM GROUP TRANSFER REACTIONS
-
Improved catalysts useful in a number of organic synthesis reactions such as olefin metathesis and atom or group transfer reactions are made by bringing into contact amulti-coordinated metal complex comprising a multidentate Schiff base ligand, and one or more other ligands, with an acid under conditions such that said acid is able to at least partly cleave a bond between the metal and the multidentate Schiff base ligand of said metal complex, optionally through intermediate protonation of said Schiff base ligand.

- Synthesis and spectral [IR, 1H, 13C, and 11B] properties of 2-(N-arylsalicylaldimino)- 4,4,5,5-tetramethyl-1,3,2-dioxaborolanes
-
Reactions in 1:1 molar ratio of 2-isopropoxy-4, 4, 5, 5tetramethyl-1, 3, 2-dioxaborolane with N-arylsali-cylaldimines (LH=HOC6 H4CH=NC6H5, HOC6H4CH=NC6H4Me2-2,6, HOC6H4CH=NC6H2Me3-2,4,6, HOC6H4CH=NC6H3Et2-2, 6, and HOC6H4CH=NC6H3Pr2-2, 6 in benzene afford new cyclic compounds of boron containing pinacolate and salicylaldiminate groups. These new derivatives have been characterized by elemental analysis and spectroscopic [IR, NMR (1H, 13C, and 11B)] studies as well as by molecular weight determinations.
