Green Lewis acid catalysis in organic synthesis*
New types of Lewis acids as water-stable catalysts have been developed. Metal salts such as rare earth metal triflates can be used in carbon–carbon bond-forming reactions in aqueous media. These salts can be recovered after the reactions and reused. Furthermore, Lewis acid–surfactant-combined catalysts, which can be used for reactions in water without using any organic solvents, have been also ...
متن کاملNovel Lewis acid catalysis in organic synthesis
Cationic zirconocene or hafnocene complexes serve as a novel class of Lewis acid with unique reactivities, which are to be exploited in organic synthesis. Four categories of reactivities are discussed, that is, (A) C-F bond activation/cleavage, (B) Coordinative activation of ether linkages, (C) Carbonyl activation, and (D) C-0 bond cleavage via zirconocene alkoxide. Introduction Lewis acid-prom...
متن کاملLewis base catalysis in organic synthesis.
The legacy of Gilbert Newton Lewis (1875-1946) pervades the lexicon of chemical bonding and reactivity. The power of his concept of donor-acceptor bonding is evident in the eponymous foundations of electron-pair acceptors (Lewis acids) and donors (Lewis bases). Lewis recognized that acids are not restricted to those substances that contain hydrogen (Brønsted acids), and helped overthrow the "mo...
متن کاملBidentate Lewis acid catalysts in asymmetric synthesis*
The chemistry of bidentate Lewis acids belongs to an unexplored field of science, and so far has been only poorly studied. This paper illustrates the design of several bidentate Al and Ti Lewis acids, and their successful application to selective organic synthesis, particularly to asymmetric synthesis. For example, a new, chiral bidentate Ti(IV) complex is successfully designed by adding commer...
متن کاملPotassium hydride in paraffin: a useful base for organic synthesis.
The preparation of potassium hydride as a 1:1 homogenate with paraffin, termed KH(P), is reported. KH(P), a solid at room temperature, is stable without special handling. On suspension in THF with a phosphonium salt, KH(P) rapidly generates the ylide. Wittig condensation with aromatic, aliphatic, and alpha,beta-unsaturated aldehydes proceeds with high Z selectivity. KH(P) should be a generally ...
