As cannabis legalization reforms are underway, there is some concern that non-profit, ‘middle ground’ options may remain under-researched and thus less visible. This book offers an in-depth account of one of the possible ‘middle ground’ models for the supply of cannabis: the Cannabis Social Club. Cannabis Social Clubs (CSCs) are typically formal, non-profit associations of adult cannabis users who produce and distribute that substance close to or at cost price among themselves. They constitute an user-driven model for the supply of cannabis. In most jurisdictions, CSCs remain a grass roots, unregulated initiative of groups of users, but the model has been legalized in Uruguay and Mal...
The catalytic epoxidation of olefins plays an important role in the industrial production of several commodity compounds, as well as in the synthesis of many intermediates, fine chemicals, and pharmaceuticals. The scale of production ranges from millions of tons per year to a few grams per year. The diversity of catalysts is large and encompasses all the known categories of catalyst type: homogeneous, heterogeneous, and biological. This book summarizes the current status in these fields concentrating on rates, kinetics, and reaction mechanisms, but also covers broad topics including modeling, computational simulation, process concepts, spectroscopy and new catalyst development. The similarities and distinctions between the different reaction systems are compared, and the latest advances are described. - Comprehensive listing of epoxide products - Broad comparison of turnover frequencies of homogeneous, hetergeneous, main-group, biomimetic and biological catalysts - Analysis of the general strengths and weaknesses of varied catalytic systems - Detailed description of the mechanisms of reaction for classical and emerging catalysts
The Handbook is part of the Handbook of Reagents for Organic Chemistry series, aiming at collecting articles on a particular theme that individual researchers in academia or industry can use on a daily basis. The Handbook starts with a section discussing the most important aspects of heteroarene functionalization. The introduction is followed by the alphabetical listing of the most relevant reagents drawn from the EROS database. The Editor, André Charette from the University of Montreal, has selected 120 reagent descriptions, many of them updated with heteroarene-specific reactions for this Handbook. Following the standard format for EROS, each article contains an overview of the synthesis ...
Reprint of the original, first published in 1873.
Providing a glimpse into the future, the young scientists contributing here were considered to be the most important for tomorrow's chemistry and materials science. They present the state of the art in their particular fields of research, with topics ranging from new synthetic pathways and nanotechnology to green chemistry. Of major interest to organic chemists, materials scientists and biochemists.
The present issue, Volume 2 of "Boron Compounds" 4th Supplement of the Gmelin Hand book, updates the previous issues by reporting the literature on boron-oxygen systems published up to 1988. For some important recent developments literature is covered through mid-1992; this concerns, for example, the compounds ~-Ba3[B306h and U[B305J which became of interest as materials with nonlinear optical properties. The volume directly com plements the earlier "Boron Compounds" 3rd Supplement Volume 2. In the original literature, alternative formulations are frequently used for the same com pound. This is especially true for many borates. Often, these species are neither completely heteropolar nor cova...
From reviews of previous volumes: "Essential for chemistry collections at the university and research levels." -New York Public Library "Highly recommended...lots of succinct, practical information on recent developments...in a format that is easy to use. The reagents are taken up in alphabetical order (common usage names, not CAS indexing code names), sometimes several to a page, sometimes several pages to a reagent. One can expect to find how to make the reagent (in loose terms), or where it can be bought, what is is good for, and where to seek complete details. As with previous volumes, one can profit from just browsing, even if one does not feel a need to look up any particular subject. It is thus a secondary function of the book to help one keep abreast of the field, and it would be a rare chemist who would not learn something new and useful from a casual perusal of the pages." -Journal of the American Chemical Society
