VANOL and VAPOL ligands are known to react with three equivalents of B(OPh)3 to form a catalytic species that contains a boroxinate core with three boron atoms, and these have proven to be effective catalysts for a number of reactions. However, it wa

The catalytic asymmetric aziridination of imines and diazo com- pounds (AZ reaction) mediated by boroxinate catalysts derived from the VANOL and VAPOL ligands was in- vestigated with chiral imines derived from five different chiral, disubstituted, me

An electride has been synthesized that is stable to auto-decomposition at room temperature. The key was the theoretically directed synthesis of a per-aza analogue of cryptand[2.2.2] in which each of the linking arms contains a piperazine ring. This c

The first barium sodide, with stoichiometry Ba(2+)(H(5)Azacryptand[2.2.2](-))Na(-).2MeNH(2), was synthesized by the reaction of Ba, Na, and H(6)Azacryptand[2.2.2] in NH(3)-MeNH(2) solution. It was characterized by X-ray crystallography, (23)Na MAS NM

The macrobicyclic Schiff base cryptand, 1, with a m-phenyl group in each of the arms was reduced in tertrahydrofuran with the alkali metals Na through Cs to yield mono-, di-, and trianions. The crystal structure of a salt of 1-, formed by reduction o

Crystalline Cs+(18-crown-6)2e- was found to be a linear chain Heisenberg antiferromagnet (J/kB = −38.3 K). It undergoes a slow, irreversible transition above ∼230 K from a crystalline low temperature (LT) phase to a disordered Curie−Weiss param

Studies are described that were designed to determine the structure of the active catalyst in the asymmetric catalytic aziridination of imines with ethyl diazoacetate (AZ reaction). Evidence suggests that the active catalyst contains a boroxine ring
