By A.J.Boulton A.R. Katritzky

(from preface)Volume 27 includes 4 contributions. Black and Doyle speak about '' l-Azabicyclo[3.1.0]hexanes and Analogs with extra Heteroatom Substitution.'' half II of the therapy of ''Heteroaromatic Radicals'' by way of Hanson offers with radicals with workforce VI heteroatoms and completes the overview of the heteroaromatic unfastened radicals began in quantity 25. In ''The 1,2- and 1,3-Dithiolium Ions.'' Lozac'h and Stavaux increase thus far the overview by means of Prinzbach and Futterer which seemed in 1966 in quantity 7 of this e-book. ultimately, Grimmett has up to date his personal evaluate of im-idazole chemistry which seemed in 1970 in quantity 12.
