Title: The Innovative Contributions of Frederick L. Herman
Introduction
Frederick L. Herman is a notable inventor based in Allentown, PA (US). He has made significant contributions to the field of chemistry, particularly in the development of metallated and substituted alkynes. With a total of 8 patents to his name, his work has had a considerable impact on various applications in polymer science.
Latest Patents
One of his latest patents involves a process for making metallated and substituted alkynes from feedstocks that include alkadienes containing allenic unsaturation. This innovative reaction begins with the isomerization of the allenic hydrocarbon and any internal alkyne, while simultaneously metallating the resultant terminal alkynes with an alkali metal. The reaction is conducted at relatively low temperatures in an inert solvent, such as diethylether. Once metallation is complete, the mixture can be treated with suitable electrophiles, like chlorotrimethylsilane, to replace the alkali metal with the desired substituent. The products formed are valuable as monomers for preparing polymers with diverse properties, including asymmetric membranes for gas separation.
