Gold(I)-Catalyzed Amination of Allylic Alcohols with Cyclic Ureas and Related Nucleophiles
摘要:
A 1:1 mixture of [P(t-Bu)(2)-o-biphenyl]AuCl and AgSbF6 catalyzes the Intermolecular amination of allylic alcohols with 1-methylimidazolidin-2-one and related nucleophiles that, in the case of gamma-unsubstituted or gamma-methyl-substituted allylic alcohols, occurs with high gamma-regloselectivity and syn-stereoselectivity.
Organic polymers having water contact angles of 20° or smaller, preferably 7° or smaller and equipped with both high wettability and high transparency. The organic polymers may contain as partial structures polar structures of about 3 debyes or higher in dipole moment and are available especially from polymerization of polymerizable compounds having alkylene(thio)urea structures.
