Description
Summary:Abstract Boron-containing aromatic systems exhibit unique electronic properties and reactivities that have been extensively studied for a long time. This review highlights the recent developments in the synthesis of aromatic boron-containing heterocycles. The organization of the contents is based on the sizes of rings and the heteroatoms other than boron. Early work in the field is briefly introduced, but the main focus is on recent reports published during the period of 2008 through 2016. 1 Introduction 2 Five-Membered Rings 2.1 Borole Derivatives 2.2 B,N-Heterocycles 2.3 B,O-Heterocycles 3 Six-Membered Rings 3.1 Borabenzene Derivatives 3.2 Boratabenzene Derivatives 3.3 1,4-Diborabenzene 3.4 B,N-Heterocycles 3.5 B,E-Heterocycles (E = O, S, P, Te) 4 Three-Membered Rings 4.1 Borirenes 4.2 Azadiboriridines 4.3 Triboracyclopropenyl Dianion 5 Four-Membered Rings 5.1 bicyclo -Tetraborane(4) 5.2 1,3-Diborete 5.3 B,E-Heterocycles (E = N, P, As, Sb, Bi, O, S, Se) 6 Seven-Membered Rings (Borepines) 7 Conclusion and Perspective
