摘要:由咪唑基亚烷基催化剂和α,β-不饱和醛在四面体中间体中进行的氢转移形成了共轭breslow中间体.这是关键步骤,它通过向芳基醛中添加均烯酸酯来影响nhc催化的γ-丁内酯的形成效率.一种新型的邻位烷氧基侧基的咪唑基亚烷基催化剂描述了-N-芳基.这种催化剂有助于形成共轭的breslow中间体.对提供γ-丁内酯的均烯酸酯环化反应速率常数的研究表明,在n-芳基取代基的适当位置引入氧原子可以提高咪唑基亚烷基催化剂的效率.结构和机理研究表明,烷氧基侧基可以靠近四面体中间体的质子,从而促进质子转移.

摘要:A thermosensitive recording material comprising a thermosensitive layer provided on a substrate, and the thermosensitive layer comprises as main ingredients a leuco dye and a developer to make colored state of said leuco dye when heated, wherein the developer is an oligomer composition obtained from the reaction of a polyvalent isocyanate compound represented by following Formula (I) with an aromatic amine represented by following Formula (II); n nwhere X represents a try- or more-valent group, a represents an integer numeral of 3 or more, b and c represent respectively integer numerals in the range of 0 to 5 and they satisfy a relation of b+c=1 to 5, Z represents hydrogen atom, alkyl group, allyl group or aryl group, and the aryl group may include condensed ling structure thereof, and d represents an integer numeral in the range of 0 to 4. This developer shows excellent reliabilities of both image and background area, and also shows an excellent color-developing characteristics (color developing sensitivity and image density).
