Asymmetric addition of chiral boron-ate complexes to cyclic iminium ions [PDF]
Boron-ate complexes derived from enantioenriched secondary benzylic boronic esters and aryl lithiums have been reacted with quinolinium, pyridinium and dihydroisoquinolinium salts to give enantioenriched heterocyclic structures with very high ...

(Phosphanyl)phosphaketenes as building blocks for novel phosphorus heterocycles. [PDF]
Although BH3 simply coordinates the endocyclic P of (phospholidino)phosphaketene 1Dipp , the bulkier B(C6F5)3 gives rise to a zwitterionic diphosphirenium, which is a novel type of 2π-electron aromatic system as shown by the calculated NICS values. While
