About this collection

This collection is Guest Edited by Editorial Board Member  Professor Russell Cox . It contains selected reviews, communications and full papers published from 2013 to 2015. The collection brings together articles with the continued aim of inspiring new authors to submit their best work to the journal, but also to highlight great work by regular authors. These articles are already among the most highly cited works in the journal, illustrating their impact. The subject areas include those traditionally regarded as organic, such as synthesis, catalysis, heterocyclic and organometallic chemistry, natural products chemistry and method development. In addition, it also includes articles from overlapping areas including green chemistry, fuel production, ionic solvents and materials chemistry, where there is a strong organic and biological component. Underpinning all are theoretical and computational studies. Finally, emerging areas such as photovoltaics and chemical biology have strong organic chemistry foundations and also find a natural home in this RSC Advances collection. Overall, this selection aims to illustrate the breadth, depth and impact of papers published in RSC Advances in the area of organic chemistry and stimulate new submissions in these and allied areas.
