Title: Shrikant Vishwanath Dighe: Innovator in Thiol Compounds and Polyenes
Introduction
Shrikant Vishwanath Dighe is an accomplished inventor based in Bethesda, MD, known for his significant contributions to the field of chemistry. With a total of two patents to his name, Dighe's work has notably advanced the understanding and application of thiol-containing compounds and polyenes in various industrial processes.
Latest Patents
Dighe's most recent patents include innovations focused on thiol containing compounds and their preparation. This invention highlights thiol compounds that are devoid of hydrolytically sensitive groupings, making them particularly beneficial as polymerization transfer agents or curing agents in polymer systems that involve polyenes and free radical initiators. The process involves reacting a polyol with an allylic halide to create a poly(unsaturated ether), which is then modified through free radical catalyzed addition of SH groups from a thiolcarboxylic acid, yielding desired thiols or polythiol derivatives. An alternative method allows for direct conversion of the poly(unsaturated ether) to thiols using H2S in a single-step reaction. Furthermore, he has explored polyenes derived from diphenyl ethers, demonstrating the potential to react them with dialkylamine to produce complex compounds.
