Synthesis of a novel titanium complex catalyst and its catalytic performance for olefin polymerization

A phenoxy-ester Ti based complex of bis[5-methyl-3-trimethylsilyl phenyl salicylate]titanium(IV) dichloride was prepared for olefin polymerization. The structures of the ligand and the complex were characterized using infrared spectrometer, nuclear magnet

Etching a coordination of the transition metal organic complex and its olefin polymerization catalyst system and in the catalytic system used in the polymerization of olefins

The invention discloses a novel phenoxy ester coordinated transition metal organic complex, an olefin polymerization catalytic system comprising the same and an application of the catalytic system. The catalytic system comprises (A) a transition metal org

Continuous-flow synthesis of trimethylsilylphenyl perfluorosulfonate benzyne precursors

2-(Trimethylsilyl)phenyl perfluorosulfonated aryne precursors may now be accessed using flow chemistry, enabling the fast preparation of pure compounds with no requirement for low temperature lithiation or column chromatography. The process has been adapted to novel nonaflate precursors, utilizing the cheaper and more user-friendly nonaflyl fluoride reagent. The resultant nonaflates are shown to successfully participate in a range of aryne reaction classes.

Regiocomplementary cycloaddition reactions of boryl- and silylbenzynes with 1,3-dipoles: Selective synthesis of benzo-fused azole derivatives

Benzo-fused nitrogen-containing heterocycles are abundant in biologically active compounds. One of the most important methods for preparing such heterocycles is the (3 + 2) cycloaddition reaction of benzynes with 1,3-dipolar compounds. However, the reacti

Highly atom economical uncatalysed and I2-catalysed silylation of phenols, alcohols and carbohydrates, using HMDS under solvent-free reaction conditions (SFRC)

An uncatalysed silylation of phenols, regardless on the aggregate state and nature of the substituents with 0.55 equiv of HMDS under solvent-free reaction conditions (SFRC) at room temperature is reported. Sterically hindered phenols, carbohydrates and most of the alcohols additionally required a catalytic amount (up to 2 mol %) of iodine. The reaction protocol is very simple; obtaining a pure product, particularly of uncatalysed reactions, was frequently a completely solvent-free process.

Preparation and regioselective Diels-Alder reactions of borylbenzynes: Synthesis of functionalized arylboronates

(Figure Presented) B+ [4+2]: 3-Borylbenzynes undergo Diels-Alder reactions with substituted furans and pyrroles to give highly functionalized arylboronic acid derivatives with either good or exclusive regioselectivities (see picture). The effect of the boryl group on the regioselectivity arises from electronic rather than steric effects.

Synthesis of biaryl compounds through three-component assembly: Ambidentate effect of the tert-butyldimethylsilyl group for regioselective diels-alder and hiyama coupling reactions

Two for the price of one: A method has been developed for the regiocontrolled synthesis of multisubstituted biaryl derivatives. This protocol involves the use of the tert-butyldimethylsilyl (TBDMS) group to direct the regioselective Diels-Alder reaction of a 3-TBDMS-benzyne with a furan derivative and a subsequent Hiyama cross-coupling reaction of the TBDMS group with aryl iodides (see scheme).

Expedient, high-yielding synthesis of silyl-substituted salen ligands

Described is an efficient synthesis of silyl-substituted salen ligands, used for the preparation of enantioselective catalysts. The salicylaldehyde precursors are synthesized from the silyl ethers of 2,6-dibromophenols via a one-pot double lithium halogen

An efficient procedure for the synthesis of ortho-trialkylsilylaryl triflates: Easy access to precursors of functionalized arynes

o-Trialkylsilylaryl triflates which are useful aryne precursors are prepared from o-bromophenols by an efficient, one-pot procedure involving O-silylation, metal-halogen exchange, O- to C-silyl migration, and entrapment of the phenoxide with triflic anhydride.
