• REGIOCHEMICAL CONTROL IN THE 1,2-CARBONYL TRANSPOSITION OF α,α′-DIMETHYLENE SYSTEMS THROUGH REGIOSELECTIVE SULFENYLATION OF TOSYLHYDRAZONE DIANIONS
  作者：Tetsuya Mimura、Takeshi Nakai

  DOI：10.1246/cl.1980.931

  日期：1980.8.5

  The regiochemical outcomes are described in the 1,2-carbonyl shift of α,α′-dimethylene systems which relies upon the regioselective sulfenylation of tosylhydrazone dianions leading to the enol thioethers of transposed ketones. Notably, a high regiospecificity was obtained with β-methyl- and β,β-dimethylcyclohexanone without any attempts to separate the stereoisomers of the hydrazones.

  区域化学结果在 α,α'-二亚甲基系统的 1,2-羰基位移中进行了描述，该系统依赖于甲苯磺酰腙二价阴离子的区域选择性磺基化，导致转位酮的烯醇硫醚。值得注意的是，β-甲基-和β，β-二甲基环己酮获得了高区域特异性，而无需尝试分离腙的立体异构体。

  The present invention is a positive photosensitive resin composition including: (A) an alkali-soluble resin containing at least one or more structures selected from a polyimide structure, a polybenzoxazole structure, a polyamide-imide structure, and a precursor structure thereof; (B) a crosslinkable polymer compound containing a structural unit represented by the following general formula (1) and having a group crosslinked with the component (A); and (C) a compound having a quinonediazide structure for serving as a photosensitizer to generate an acid by light and increase a dissolution speed to an alkaline aqueous solution. An object of the present invention is to provide a positive photosensitive resin composition and a positive photosensitive dry film that enable formation of a fine pattern and high resolution, have excellent mechanical characteristics even when cured at low temperatures, and have no degradation in adhesive force between before and after a high temperature and high humidity test.
