The synthesis of chiral C2-symmetric N-heterocyclic carbene complexes
The quaternisation of 1-substituted-azoles with a, w-dihaloalkanes furnished the diazolium salts. Conversion of the salts by deprotonation in the presence of sulphur generated the corresponding dithiones. A series of propylene diimidazolium salts and thiones gave an insight into the ease of handling...
