each is not a phenyl group having substituents at an ortho and/or a meta position), and a composition consisting of the compound and a diazodisulfone compound are disclosed. Use of the compound or the compound as an acid generator for resists produces the effects of improving the profiles of ultra-fine patterns or diminishing sidewall irregularities in ultra-fine patterns. The compound is also useful as a cationic photopolymerization initiator.

We communicate a simple method for the transferhydrogenation of aromatic aldehydes in i-PrOH effected by the cost-effective and easy-to-handle [Cr(CO)6]. The reactions are readily carried in Ar-flushed tubes without further need of special equipment. Functional groups are widely tolerated and, if desired, the catalytic transformations can be further promoted through the addition of trimethylamine
我们介绍了一种在i -PrOH中转移氢化芳香醛的简单方法,该方法受成本效益高且易于处理的 [Cr(CO) 6 ] 的影响。反应很容易在 Ar 冲洗管中进行,无需进一步的特殊设备。官能团具有广泛的耐受性,如果需要,可以通过添加三甲胺N-氧化物 (TMAO) 进一步促进催化转化。这为在温和反应条件下处理热不稳定底物铺平了道路。此外,所介绍的方法适用于苯甲醇衍生物的氘代。
