WebDuring attempts to prepare the even more sterically congested hydrocarbon hexaphenylethane, he correctly identified the triphenylmethyl radical, the first persistent radical to be discovered, and is thus known as the founder of radical chemistry. The work was later followed up by Wilhelm Schlenk. WebThe most widely used protective group in cellulose chemistry is the triphenylmethyl (trityl) moiety. First attempts to introduce this ether function in cellulose were described by Husemann and Seifert 560 exploiting N-ethylpyridinium chloride melts for the homogeneous phase tritylation. chelsey shaw worth clark realty
