Microwave-Assisted Cobinamide Synthesis
The Journal of Organic Chemistry, 2014We present a new method for the preparation of cobinamide (CN)2Cbi, a vitamin B12 precursor, that should allow its broader utility. Treatment of vitamin B12 with only NaCN and heating in a microwave reactor affords (CN)2Cbi as the sole product. The purification procedure was greatly simplified, allowing for easy isolation of the product in 94% yield ...

Microwave Synthesis of Nanoporous Materials
ChemPhysChem, 2006AbstractStudies in the last decade suggest that microwave energy may have a unique ability to influence chemical processes. These include chemical and materials syntheses as well as separations. Specifically, recent studies have documented a significantly reduced time for fabricating zeolites, mixed oxide and mesoporous molecular sieves by employing ...

Microwave Synthesis of Cyanine Dyes
Journal of Microwave Power and Electromagnetic Energy, 2010Heptamethine cyanine dyes are a class of near infrared (NIR) dyes that have captured the interest of the scientific community. Although applications that utilize NIR fluorescence technology are rapidly expanding, progress is limited by the lack of availability and cost of suitable compounds that can be utilized as labels and/or probes.

Microwave-Assisted Organophosphorus Synthesis
Current Organic Chemistry, 2013The spread of microwave (MW) equipment has brought about a tremendous development in synthetic organic chemistry. This environmentally friendly methodology, associated often with solventless conditions, has also had a positive impact on organophosphorus chemistry, allowing new reactions to be carried out, or increasing the rate, selectivity and yield.
