This useful reference device is an prepared annual overview of synthetically important details. It abstracts artificial reactions from the main chemistry journals of the prior yr and contains reactions and techniques thatare new and fairly common. The reactions are offered in a handy pictorial structure designed for fast visible retrieval of data.

The use of the N-alkylated macrocycles in place of the unmodiﬁed analogs inﬂuences many properties of the binuclear complexes, including color, molecular and electronic structure, hydrogen bonding interactions, redox potential, complex stability, and ground spin-state. The reactivity is also greatly affected as shown by the activation and transformation of small molecules such as CO2, the highly diastereoselective cis-bromination of a,b-unsaturated carboxylate coligands, and some regioselective Diels–Alder reactions.
At the same time chelating guanidine ligands have been independently developed by the group of G. Henkel . 2. 2 Selected bidentate, tridentate and tetradentate guanidine ligands developed in this research program. Tame ¼ 1,1,1-Tris(aminomethyl)ethane, Tren ¼ tris(2aminoethyl)amine. This research program focussed on the guanidine coordination chemistry of copper and zinc. Two working concepts were followed. It was proposed that superbasic tripodal and sterically demanding tren-derived guanidine ligands when coordinated to copper(I) would create a very electron-rich metal center perfectly embedded in a molecular pocket.
