Boratranes synthesis are predictably based on the reactions of triethanolamine derivatives with boric acid, or trialkyl borate and require prolonged heating reagents under reflux. Herein, authors report an efficient unexpected boratranes featuring one hand three six-membered chelating ring two five-membered other a trans-annular boron atom is bound to nitrogen, oxygen carbon atom. These novel h...

A series of new dicationic dihydrogen complexes of ruthenium of the type cis-[(dppm)2Ru(η-H2)(L)][BF4]2 (dppm = Ph2PCH2PPh2; L = phosphite) have been prepared by protonating the precursor hydride complexes cis[(dppm)2Ru(H)(L)][BF4] using HBF4•Et2O. The precursor hydride complexes have been obtained from trans-[(dppm)2Ru(H)(L)][BF4] (L = phosphite) via a rare acidcatalysed isomerization reaction...
