The Science of Synthesis Editorial Board,together with the volume editors and authors, is constantly reviewing the whole field of synthetic organic chemistry as presented in Science of Synthesis and evaluating significant developments in synthetic methodology. Four annual volumes updating content across all categories ensure that you always have access to state-of-the-art synthetic methodology.

Content of this volume: Organometallic Complexes of Gold, Benzylstannanes, Allylstannanes, Furans, Thiophenes, Thiophene 1,1-Dioxides, and Thiophene 1-Oxides, Synthesis with Retention of the Functional Group, Alkanesulfonic Acids and Acyclic Derivatives.
