Abstract:
A series of new chiral zwitterionic NNO-scorpionate mononuclear zinc alkyls [Zn(R)(κ3-NNO)]Br was developed in very high yields via suitable quaternization in the scorpionate ligand. These zwitterionic complexes performed as bifunctional catalysts and exhibited improved catalytic activity for the fixation of CO2 into cyclic carbonates compared to the neutral analog mononuclear [Zn(R)(κ3-NNO)] and binuclear [Zn(R)(κ2-NNμ-O)Zn(R)2] compounds. The catalyst system showed a broad substrate scope and functional group tolerance under mild and solvent-free conditions.

The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
