Phenylacetylene for synthesis 536-74-3

WebIn the case of the synthesis of hexaphenylbenzene, the bicyclic intermediate readily undergoes a second cycloaddition reaction to form the desired product. Isolating the bicyclic adduct as an intermediate would require additional purification steps, which would increase the overall complexity and time of the synthesis. WebAB - A new scheme for the synthesis of phenylacetylene dendritic macromolecules is described which greatly facilitates the large-scale production of high molecular weight monodendrons. Simply by inverting the monomer protecting group scheme from B2Ap to A2Bp (where A = ArC≡CH; B = ArI; Ap and Bp are protected versions of these groups), we ... optimize windows 11 reddit
