Copper-Mediated Nucleophilic Addition/Cascade Cyclization of Aryl Diynes

Treatment of diyne substrates with sulfinate salts under the action of copper(II) triflate results in a cascade cyclization reaction. The reaction involves nucleophilic addition of the sulfinate and formation of two new C-C bonds with concomitant cleavage of an aryl C-H bond. The reaction proceeds in good yields with a range of diyne precursors and sulfinate salts. Preliminary mechanistic analysis reveals a rare example of an operative ionic mechanism in contrast to other related cyclizations.

TITANIUM (IV) COMPOUNDS AND METHODS OF FORMING HETEROCYCLIC COMPOUNDS USING SAME

The present disclosure provides Titanium (IV) compounds and methods of making heterocyclic compounds such as pyrroles using Titanium (IV) compounds. In certain embodiments, the Titanium (IV) compound is present in catalytic amounts.

Formation of C(sp2) Boronate Esters by Borylative Cyclization of Alkynes Using BCl3

BCl3is an inexpensive electrophile which induces the borylative cyclization of a wide range of substituted alkynes to regioselectively form polycycles containing synthetically versatile C(sp2) boronate esters. It proceeds rapidly, with good yields and is compatible with a range of functional groups and substitution patterns. Intermolecular 1,2-carboboration of alkynes is also achieved using BCl3to generate trisubstituted vinyl boronate esters.

Phosphine-promoted cyclization of dicyclopropenones

A novel phosphine-promoted intramolecular cyclization of dicyclopropenones 1 has been described in this contribution. A variety of 2,3-dihydro-1H-indene-4, 6-diol derivatives 2 and hexahydropentalen-2-one derivatives 3 were obtained selectively in moderat

Ruthenium-catalyzed cascade reactions of diynes with norbornadiene -synthesis of norbornene derivatives

Norbomene derivatives 7-11 were prepared from norbornadiene and the corresponding diynes by Ru-catalyzed [(2+2)+2] cycloaddition and subsequent transfer hydrogenation. The structure and stereochemistry of the cycloadducts were confirmed by X-ray crystal a

Iridium- and rhodium-catalyzed [2+2+2] cycloadditions of diynes with maleimide: A new synthetic route to highly substituted phthalimides

The [2+2+2] cycloaddition of maleimide with α,ω-diynes in the presence of [IrCl(cod)]2 or [RhCl(cod)]2 and DPPE gives cyclohexadiene derivatives which are readily aromatized with DDQ or MnO 2. This two-step procedure gives

A zirconocene-coupling route to substituted poly(p- phenylenedienylene)s: Band Gap tuning via conformational control

A series of substituted poly(p-phenylenediyne)s (1a-f) was synthesized by the palladium-catalyzed cross-coupling condensation of terminal dialkynylalkanes with substituted diiodobenzenes. Polymerizations were conducted with 1,4-diiodo-5-hexoxy-2-methoxybe
