We report a new electrochemical supporting-electrolyte-free method for synthesizing ureas, carbamates, and thiocarbamates via the oxidation of oxamic acids. This simple, practical, phosgene-free route includes generation an isocyanate intermediate in situ anodic decarboxylation acid presence organic base, followed by one-pot addition suitable nucleophiles to afford corresponding thiocarbamates....

D uring the past decade the method of functional cranial analysis has been developed in our laboratory. The basic postulates and the experimental and clinical supporting data have been published extensively elsewhere.4-“Y The orthodontic specialty recently became aware of this analytical technique, with particular interest being expressed in the derivat,i\-e concept of the Jurrctionul matrix. I...
