Science of Synthesis 4.21, the latest release of Thieme’s reference resource for reliable synthetic methods, includes nine knowledge updates. Among others, chapters covering the synthesis of germylenes as well as borazines and 1,2-diimines and 1,3-diimines have been added. SOS now also offers the possibility to easily share links to Science of Synthesis articles by e-mail or on social media.
In “Free Radicals: Fundamentals and Applications in Organic Synthesis”, the two renowned radical chemists based at Sorbonne University in Paris present highlights in the selective generation of organic radicals and in their use in organic synthetic reactions in a readily accessible and practical fashion. Volume 2 was added in the previous SOS update 4.20. The latest release of SOS includes Volume 1, which covers a variety of topics such as modelling radicals and their reactivities, electron catalysis and intermolecular radical C-H functionalization, in reviews that are compiled by experts in each area.
Other highlights of this release are updates on arylstannanes (J. Vrána and A. Růžička) and α-boryl carbonyl compounds (A. Trofimova, M. Sirvinskas, and A. K. Yudin), including MIDA boronates, as well as an update on the synthesis of thiopyrylium salts (M. Wang and X. Jiang). Furthermore, the latest version features an update on cyclobutanes (Y. Xiong, R. Guo, and G. Z. Zhang), with a focus on transition-metal catalyzed and photochemical approaches to these strained carbocyclic species.
SOS 4.21 includes a revised chapter on the synthesis of germylenes (N. Takeda). New chapters cover 1,2-diimines (R. Isovitsch) and 1,3-diimines, also known as β-diketimines (K. Chand, Umesh, D. P. Dorairaj, and S. C. N. Hsu), both of which are important ligands for transition-metal complexes. SoS now also features chapters on piperazines (Z.-S. Ye), saturated cyclic diamines that occur widely in natural products and pharmaceuticals, and azaborines (borazines) (G. H. M. Davies and S. R. Wisniewski).
Science of Synthesis now incorporates an article sharing function. One can now easily share links to Science of Synthesis articles by e-mail, on Twitter, Facebook, or LinkedIn using the button located at the top right-hand side of each page.
