Chemistry is traditionally divided into organic and inorganic chemistry. Recommanded Product: 72287-26-4, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 72287-26-4

Palladium complex PdCl2(dppf) and nickel complex NiCl2(dppe) catalyze cross-coupling of unsaturated aryloxy carbohydrates with phenylmagnesium bromide. The nickel catalyst leads to inversion of configuration at the anomeric center while only retention occurs in the case of the palladium catalyst. This quite unusal retention is probably due to the influence of the ring oxygen atom.

A copper free [Pd]-catalyzed domino intramolecular Heck and intermolecular decarboxylative Sonogashira couplings, for the synthesis of alkyne bearing heterocyclic compounds with a quaternary carbon atom, is described. Notably, this dual bond forming strategy is successful in water solvent, under microwave irradiation. This one-pot operation enabled the formation of a variety of dihydrobenzofurans, indolines and oxindoles, in very good to near quantitative yields. Notably, unlike earlier reports, the present strategy is successful in delivering the products with short alkyl substituents on acetylene carbon, which is first of its kind.

The synthesis of unsymmetrical sulfides was carried out in high yields by the palladium-catalyzed cross-coupling reaction of 9-organothio-9-borabicyclo[3.3.1]nonane (9-RS-9-BBN) with organic electrophiles, such as iodoarenes, 1-iodo-1-alkenes, allyl carbonate and propargyl carbonate. Iodoarenes and 1-iodo-1-atkenes were smoothly converted into the corresponding sulfides at 50 C in the presence of PdC12(dppf) (3 mol%) and K3PO4 (3 equiv.) in DMF. In contrast, the cross-coupling reaction of 9-RS-9-BBN with allyl or propargyl carbonates occurred in DMF without the assistance of a base. Both reactions catalyzed by Pd(dba)2-dppf regioselectively produced allyl and allenyl sulfides in excellent yields. The scope and limitations of the reactions, as well as the effects of varying the reaction conditions, are discussed.

A catalytic method to synthesize 1,3,-dienes from propargylic precursors is reported. This palladium-catalyzed carbon-nitrogen bond-forming reaction furnishes 2-amino-1,3-dienes in excellent yields (up to 98%) and shows a broad tolerance to functional group diversity. The reaction has been demonstrated for over 30 amine substrates, including anilines and indoles, and proceeds under mild neutral conditions. The resulting 1,3-dienes are of great synthetic interest because of their further reaction potential.
