    • Dialkyl malonate/alkyl acrylate Michael addition product mixtures having at least three acceptor moieties in a substantial number of the molecules can be consistently prepared without the need for long reaction times or the use of a large excess of the acceptor when the reaction is effected by gradually adding one molar proportion of a dialkyl malonate to at least three molar proportions of an alkyl acrylate which has been preheated to 60.degree.-80.degree. C. in admixture with an initiator and a phase transfer catalyst. In a preferred embodiment, the preheated mixture is maintained at 60.degree.-80.degree. C. for at least one hour before the dialkyl malonate is added in order to increase the percentage of product composed of the heavier components.
    • 丙二酸二烷基酯/丙烯酸烷基酯在相当数量的分子中具有至少三个受体部分的迈克尔加成产物混合物可以一致地制备,而不需要长的反应时间或当反应通过逐渐地进行反应时使用大量过量的受体 将1摩尔比例的丙二酸二烷基酯加入到至少三摩尔比例的丙烯酸烷基酯中,该丙烯酸烷基酯与引发剂和相转移催化剂混合预热至60-80℃。 在优选的实施方案中,将预热的混合物在加入丙二酸二烷基酯之前保持在60-80℃至少1小时以增加由较重组分组成的产物的百分比。

    • This invention provides aromatic diimines where the diimines have imino groups with at least two carbon atoms, and either are in the form of one benzene ring having two imino groups on the ring, which imino groups are meta or para relative to each other, and in which each position ortho to an imino group bears a hydrocarbyl group, or are in the form of two benzene rings connected by an alkylene bridge and having one imino group on each ring, and in which each position ortho to an imino group bears a hydrocarbyl group. This invention also provides aromatic secondary diamines where the diamines have amino hydrocarbyl groups with at least two carbon atoms, and either are in the form of one benzene ring having two amino groups on the ring, which amino groups are meta or para relative to each other, and in which each position ortho to an amino group bears a hydrocarbyl group, or are in the form of two benzene rings connected by an alkylene bridge and having one amino group on each ring, and in which each position ortho to an amino group bears a hydrocarbyl group. Also provided are processes for forming diimines and secondary diamines from primary diamines, including the aromatic diimines and aromatic secondary diamines of the invention.
