ADVANCES IN HETEROCYCLIC CHEMISTRY V27, Volume 27

(from preface)Volume 27 contains four contributions. Black and Doyle discuss '' l-Azabicyclo[3.1.0]hexanes and Analogs with Further Heteroatom Substitution.'' Part II of the treatment of ''Heteroaromatic Radicals'' by Hanson deals with radicals with group VI heteroatoms and completes the review of the heteroaromatic free radicals begun in Volume 25. In ''The 1,2- and 1,3-Dithiolium Ions.'' Lozac'h and Stavaux bring up to date the review by Prinzbach and Futterer which appeared in 1966 in Volume 7 of this publication.
