Jason Guy Taylor was born in Nottingham, UK, and completed his M.Chem. (Hons) degree at Nottingham Trent University (2004) which included a one-year sandwich placement working as a analytical chemist at AstraZeneca. He subsequently obtained his Ph.D. degree at Imperial College London (2008), working on the development of hydroamination catalysts in the group of Dr Mimi Hii. This was followed by a two-year spell working as a post-doctoral research fellow with Professor Carlos Roque D. Correia at UNICAMP, researching the application of the Heck-Matsuda reaction in asymmetric synthesis. He is currently pursuing an independent academic research career as an associate professor at the Universidade Federal de Ouro Preto. His research interests include the synthesis of bioactive heterocyclic compounds and the development of new catalytic methodologies, and their application in the synthesis of natural products and pharmaceuticals.

Jailton Ferrari was born in Bahia, Brazil. He graduated with a bachelor’s degree in chemistry (2000) from the Universidade Estadual do Sudoeste da Bahia (UESB) and, after teaching at the high school level for a short period of time, continued his studies in organic chemistry at the Universidade Federal da Bahia (UFBA). In 2003, he received a M.Sc. degree and, in 2007, completed his Ph.D. which focussed on the investigation of new methodologies for the synthesis of 2-pyridones and their bicyclic derivatives indolizidinones and quinolizidinones under the supervision of Professor Silvio Cunha. After finishing his Ph.D., he went to Campinas (SP, Brazil) for post-doctoral studies under guidance of Professor Carlos Roque D. Correia at Universidade Estadual de Campinas (UNICAMP) in the application of the Heck-Matsuda reaction in the synthesis of arylpirroles and chiral 4-aryldehydroproline derivatives. In 2010, after leaving the Correia group, he joined the Department of Chemistry at the Universidade Federal da Paraíba (UFPB) in João Pessoa (PB, Brazil). His research interests include the development of new synthetic methodologies with transition-metal catalysts.

The search for efficient and versatile reaction medium to perform transition-metal-catalyzed reactions is a continuous challenge to the synthetic community. Organic solvents have been traditionally employed for this task, nevertheless, new environmentally friendly, safe, and economically viable alternatives are still highly sought after. In this context, herein, we present an overview of some interesting applications of aqueous microemulsions (oil-in-water, O/W) for transition metal catalyzed reactions as an alternative and promising aqueous-organic reaction medium that has been found to be a highly effective tool in overcoming some environmental or practical issues presented by traditional organic solvents.
