The reactions of several different primary amines with diorganomagnesium or dialkylzinc compounds are reported. Treatment of Mg(η 5 -C 5 H 5 ) 2 with t-BuNH 2 or DippNH 2 (Dipp = 2,6- i - Pr 2 C 6 H 3 ) leads to the adduct Mg(η 5 -C 5 H 5 )(η 2 -C 5 H 5 ...
we have reported the simple preparation of polymer supported copper complex and its successful application for the O-arylation reaction of various aryl halides with substituted phenols, N-arylation of imidazole with arylboronic acids and aryl halides and N-arylation reactions of primary amines with aryl...
Catalysts for condensation reactions of primary amines with dihydroxy aromatic compounds United rates 3,8l,349 ?atented Mar. 12, 1953 fire This invention is concerned with condensation catalysts and a process for preparing various diamines. In particular, this invention is concerned with the use an...
Herein, a baseヽontrolled protocol was developed for the C㎞ coupling of primary amines and 2ヽhlorobenzimidazoles, affording a handful of secondary or tertiary amines in a selective fashion. Moreover, this protocol was realized under transition﹎etal‐free conditions, and the variation of the ...
This work demonstrates an improvement in the Ing‐Manske and related procedures by the increase of pH of the reaction mixture after the complete disappearance of N‐substituted phthalimide. Hydrazinolysis of N‐phenylphthalimide (1a) gave 80% of the desired primary amines after 5.3h in the absence...
With primary or secondary aliphatic or aromatic amines, 1 affords N-substituted 2-alkyl (or aryl) amino-3,3-dichloro-4-dichloromethylenecyclobutenylcarboxamidinium chlorides. The reaction of 1 with phenylhydrazine proceeds with cyclization to give a cyclobutenopyrazole. The spectroscopic properties of...
A short review on the development and application of chiral primary amine catalysts in organocatalytic enantioselective reactions has been described. F Peng,Z Shao - 《Cheminform》 被引量: 308发表: 2009年 Advances in asymmetric organocatalytic reactions catalyzed by chiral primary amines A short review...
This result allowed the preparation of new dienes , , and . The second part of this paper reports preliminary results concerning the reactivity of diene towards primary amines and aldehyde equivalents. Dienals such as were found to react with primary amines to afford 1,2-dihydropyridines such as...
Kinetics of the primary cracking reactions occurring in the high pressure thermal hydrogenolysis of 1, 2, 3, 4-tetrahydronaphthalene (tetralin) and hydrindene (indan) were studied in a flow reactor at temperatures from 460° to 540°C, total pressures from 10 to 160 atm. and molar ratios of...
