Latest Patents
One of Sennyey's latest patents is a process for the synthesis of substituted carbodiimides. This invention describes a new method for synthesizing disubstituted carbodiimides, which are important intermediates in organic synthesis. The process involves a first stage of phosgenation of an N,N'-disubstituted urea in an organic solvent medium, followed by the addition of ammonia to the reaction mixture without isolating any intermediate compound. This method is noted for its simplicity, cost-effectiveness, and high yield. Disubstituted carbodiimides are particularly useful as coupling agents in peptide synthesis within pharmaceutical chemistry.
Another significant patent by Sennyey is for the manufacture of 1-bromoalkyl hydrocarbyl carbonates. This invention outlines a new process for preparing these carbonates by reacting an alpha-chlorinated carbonate with an anhydrous brominated compound in the presence of a catalyst. The resulting carbonates have applications as blocking agents for certain antibiotics and as agents for synthesizing phosphorus-containing carbonates, which can be utilized as insecticides.
