(from preface)
Volume 46 of Advances in Heterocyclic Chemistry is an "Index Volume." It contains a cumulative index of the titles of articles which have appeared in the series (Volumes 1-45), and a cumulative index of authors who have written these contributions. Additionally it contains a subject index covering Volumes 41-45, which can be used in conjunction with the subject index in Volume 40 (which covers Volumes 1-40). It is hoped that the provision of these indexes will help enhance the value of the series.
Apart from these indexes, the present volume contains four chapters spanning a wide range of heterocyclic chemistry. "1,5-Diazocines" by Perlmutter, continues his coverage of important eight-membered heterocycles (cf. "Azocines" in Volume 31, and "1,4-Diazocines" in Volume 45). Charushin, Alexeev, and Chupahkin from the Soviet Union, and Van der Plas from Holland cover reactions of 1,2,4-triazines with nucleophiles, a subject to which they bring much expertise.
There have been enormous developments in organo-boron chemistry during the last few decades, but boron-containing heterocycles are still somewhat rareties. The field is ripe for exploitation, and the chapter on this subject by Terashima and Ishikura should help in this respect.
Finally, Kadaba has contributed the first comprehensive review of the extensive chemistry of 1,2,4-triazolines. This chapter will complement the earlier review {Advances, Volume 37) on 1,2,3-triazolines by Kadaba, Stanovnik, and Tisler.
