Microwave-Assisted Cobinamide Synthesis

The Journal of Organic Chemistry, 2014
We 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 Cyanine Dyes

Journal of Microwave Power and Electromagnetic Energy, 2010
Heptamethine 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.

Synthesis of microwave filters with “reactive” nodes

2012 42nd European Microwave Conference, 2012
This paper introduces the synthesis of microwave inline filters of narrow or moderate bandwidth which include, in addition to the cavities, “reactive nodes”, which can be implemented either by lumped components or by non-resonating, open or short circuited stubs.
