Nitrogen-containing derivatives, properties

The active principle of Salvia divinorum, salvinorin A, is derived from the leaves of the plant. Chemically, salvinorin A is a neoclerodane diterpene, one of a group of nitrogen-containing terpene compounds that have psychotropic properties. Two other such compounds are tetrahydrocannabinol and absinthe. Purified salvinorin A can be obtained from an ether extract of the leaves, which is then concentrated by chromatography and repeated crystallization.

Complexes of these ligands have been described [299,300]. The NH2 group does not possess donor properties in the heterocyclic analogues of aniline - amino- derivatives of nitrogen-containing heterocycles, as for instance in structure 183 [301]. Ethyleneimine ligands also take part as donors [302]. 

Topics that have formed the subjects of reviews this year include contemporary issues in electron transport research, dynamics of bimolecular photoelectron transfer reactions, photophysical properties of functionalised fullerene derivatives, carbon-carbon bond formation via radical ions, photoinduced electron transfer processes in ketone, aldehyde, and ester synthesis, photochemical reactions between arenenitriles and benzylic donors, photo-oxidation of conjugated dienes, photoredox reactions of aromatic nitro compounds, electron transfer-mediated photochemistry of some unsaturated nitrogen-containing compounds, reactions of 02( Ag), carbon dioxide activation by aza-macrocyclic complexes, and photochromism of chalcone derivatives. ...
