Kinetics and mechanism of pyrolysis of sulphonyl hydrazones and oximes. Part 1. Contribution to reactivity from hydrazone HNN and oxime ON bond polarity

Base-Free Method for Preparation ofO-Sulfonyl Aldoximes Starting from Aldoximes and Sulfonyl Chlorides

“…[10～12] 重排、亲电胺化 [13,14] 、O-磺酰基肟氮原 子上的亲核取代 [5,15] 、经缩合反应构建碳-碳键 [16] 、 Beckmann 重排-烷基化反应 [17,18] 、热解 [6,7] 、过氧酸氧 化 [19] 等. 在现代光刻技术应用中, O-磺酰基肟作为重要 的光致酸发生剂, 已用于半导体芯片的批量生产 [20] .…”

Pyrolysis of hydrazine derivatives and related compounds with N N single bonds

“…The benzidine rearrangement is usually carried out under 67 acid catalysis, but the purely thermal benzidine rearrangement is also known. These reactions 68 have been reviewed extensively [4,5,6] and will not be repeated here. A review on short-69 contact time, radical-forming gas-phase pyrolyses, which includes some hydrazine 70 derivatives, has been published [7].…”

Red mud catalyzed one-pot synthesis of nitriles from aldehydes and hydroxylamine hydrochloride under microwave irradiation

“…30 Conversion of aldehydes into nitriles via reaction of the former with hydroxylamine sulfonic acid has also been reported. 31 Recently, conversion of arylhydrazonals into hydrazononitriles via the reaction of hydrazonals with hydroxylamine hydrochloride and sodium acetate has also been reported. The latter reaction has also been conducted in the microwave oven.…”
