Catalyst-free electrochemical sulfonylation of amines with sulfonyl hydrazide in aqueous medium.

An efficient electrochemical sulfonylation of amines with sulfonyl hydrazides under exogenous-oxidant-free and catalyst-free conditions in aqueous medium was developed. A wide variety of sulfonamides were prepared a simple electrochemical process from various cyclic or acyclic secondary amines, as well as more challenging free primary amines with equivalent amount of aryl/heteroaryl hydrazides in air under mild conditions. This protocol was found to be excellent in terms of facile scale-up, and to show great potential in the modification/synthesis of bioactive compounds.

An Empirical Analysis on the Impact of Innovation Network Structure on Crossover Innovation Performance of Emerging Technologies.

The crossover innovation springing up in emerging technologies has drawn wide attention from scholars. Innovation network, as an effective way for major innovation-driven entities towards less relevant risks and higher efficiency, can significantly affect the crossover innovation performance. This paper analyzes the evolution law of the innovation network of autonomous driving technology based on the Social Network Analysis (SNA) and by using the data on joint applications for invention patents of such technology during 2006-2020.

Effect of soaking and temperature process on the volatile compounds in soymilk made by soymilk maker.

Abstract: The influence of different processing and storage conditions on the aroma and taste of soymilk were investigated. Volatile components in soymilk were made by soymilk machine, half soybeans produced by grinding soaked with water, the other half soybeans without soaking. Then the soymilk was stored in different conditions for 24 h.
