Organic Preparations and Procedures International (OPPI) is a bimonthly publication aimed at the dissemination of information of particular importance to organic chemists engaged in synthesis. It is devoted to preparative organic chemistry, organometallic compounds, and procedures generally related to synthesis. The mission has always been to assist the practitioner by publishing reliable and reproducible procedures of the highest standards. OPPI has published articles in every area of preparative organic chemistry, from innovative new technology to nuts-and-bolts improvement in traditional synthesis. Along with experimental papers, the Journal publishes authoritative reviews on significant topics in synthesis. The editors work closely with all our authors, including those whose first language is not English, to see important work that might otherwise appear only in more restricted format get to press, thus insuring a truly worldwide audience for valuable material.
