摘要:Woodward-Hoffmann规则根据所涉及的电子数以及环状轨道重叠是否涉及表面或反面轨道重叠来预测是否允许进行一致的周环反应.伪周环反应构成第三类反应,其中正交轨道使它们成为轨道对称性,而与反应中涉及的电子数无关.基于最近关于八中心酯重排的报道,预言也将允许亚胺的等电子八中心重排.现在,我们报告说发生了这些重排,实际上,在三氯乙酰亚胺基酰基环己二酮中,至少在一种情况下,以八中心重排略胜于众所周知的六中心超人重排,

摘要:A hydroxyl-containing monomer of formula (1) is provided wherein R 1 is H, F, methyl or trifluoromethyl, R 2 and R 3 are monovalent C 1 -C 15 hydrocarbon groups, or R 2 and R 3 may form an aliphatic ring. The monomers are useful for the synthesis of polymers which have high transparency to radiation of up to 500 nm and the effect of controlling acid diffusion so that the polymers may be used as a base resin to formulate radiation-sensitive resist compositions having a high resolution.
