An iron(II)-catalyzed three-component reaction was developed for the construction of trichloromethylated 3-benzylquinoxalin-2(1H)-ones. This reaction was conducted through the trichloromethylation of alkenes with quinoxalin-2(1H)-ones using commercially available chloroform as trichloromethyl radical source, which provided a convenient approach toward trichloromethylated 3-benzylquinoxalin-2(1H)-ones.
A decarboxylative alkylation of enamides with alkyl diacyl peroxides induced by visible-light is described. The chemo-, regio- and stereoselective olefinic β-C–H alkylation generates a series of primary- and secondary alkylated...
Photo-induced facile synthesis of sulfonamidylated iminoisobenzofurans and benzoxazines was demonstrated under mild and metal-free conditions. N-sulfonylaminopyridinium salts as the easily available sulfonamidyl radical sources selectively reacted with 2-vinylbenzamides and N-(2-vinylphenyl)amides...
In this paper we studied the relationship between social capital and organizational performance, and tried to confirm whether learning orientation is an important medivariable. Through theory analysis, we built research framework and constructed Structural Equation Model, and then carried out an empirical research on 134 enterprises which come from the Peal River Delta, China.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
