scope, scalability and robustness of this unconventional catalyst-free transformation, leading to functional-ized biaryls and ultimately furnishing drug-like small molecules as well as late stage derivatization of natural compounds. In addition, the observed selectivity of the oxidative coupling reaction is related to the electronic structure of the TABs through quantum-chemical calculations and experimental

Tetracoordinate organoborate compounds, such as compounds harboring a tetraarylborate anion or a triarylalkylborate anion, are shown to exhibit a selective bacteriostatic and bactericidal effect against pathogenic Neisseria species such as N. meningitidis and N. gonorrhoeae. Exemplified active compounds include the tetraphenylborate anion (BPh4-) and a cyclic zwitterionic borinic acid ethanolamine ester. The use of such borate compounds for the treatment of pathogenic Neisseria infections is also described.
A series of acids ArB(OH)2 and Ar2BOH with an electron-withdrawing aryl group were obtained from the corresponding borates K[ArBF3] and K[Ar2BF2] by the action of MX3 (M = B, Al; X = Cl, Br) and subsequent hydrolysis. Graphical abstract
