Enantioselective synthetic methods are not only in the forefront of chemical and pharmaceutical research but activity in this area is constantly increasing. It is stimulated by the urgency to obtain drugs or compounds of medicinal interest as single anantiomers, and the keeness to synthesize natural products in nonracemic form. This volume presents seven chapters from pioneers and authorities in this rapidly expanding field.
During the past 30 years, the field of alkene polymerization over transition metal catalysts underwent several major changes:1. The list of commercial heterogeneous Ziegler-Natta catalysts for the synthesis of polyethylene and stereoregular polyolefins was completely renewed affording an unprecedented degree of control over the polymer structure.2. Research devoted to metallocene and other soluble transition-metal catalysis has vastly expanded and has shifted toward complexes of transition metals with multidentate ligands.3. Recent developments in gel permeation chromatography, temperature-rising fractionation, and crystallization fractionation provided the first reliable information about d...
Charles Peguy (1873-1914) was a French religious poet, philosophical essayist, publisher, social activist, Dreyfusard, and Catholic convert. There has recently been a renewed recognition of Peguy in France as a thinker of unique significance, a reconsideration inspired in large part by Gilles Deleuze's Difference et repetition, which ranked him with Nietzsche and Kierkegaard. In the English-speaking world, however, access to Peguy has been hindered by a scarcity of translations of his work. This first complete translation of one of his most important prose works, with accompanying interpretive introduction and notes, will introduce English-speaking readers to a new voice, which speaks in a p...
The three volumes of Language Typology and Syntactic Description offer a unique survey of syntactic and morphological structure in the languages of the world. Topics covered include parts of speech; passives; complementation; relative clauses; adverbial clauses; inflectional morphology; tense, aspect and mood; and deixis. The major ways these notions are realized in the languages of the world are explored, and the contributors provide brief sketches of relevant aspects of representative languages. Each volume is written in an accessible style with new concepts explained and exemplified as they are introduced. Although each volume can be read independently, together they provide a major work of reference that will serve as a manual for field workers and anyone interested in cross-linguistic generalizations.
Asymmetric catalysis represents still one of the major challenges in modern organic chemistry. Besides the well-established asymmetric metal-complex-catalysed syntheses and biocatalysis, the use of "pure" organic catalysts turned out to be an additional efficient tool for the synthesis of chiral building blocks. In this handbook, the experienced authors from academia and industry provide the first overview of the important use of such metal-free organic catalysts in organic chemistry. With its comprehensive description of numerous reaction types, e.g., nucleophilic substitution and addition reactions as well as cycloadditions and redox reactions, this book targets organic chemists working in industry and academia, and deserves a place in every laboratory.
