WebPhenylacetylene is hydrated to phenylacetaldehyde by way of both nucleophilic and radical additions of H 2 S followed by hydrolysis of the thioaldehyde. The addition of NH 3 and HCN to phenylacetaldehyde yields phenylalanine nitrile which is hydrolyzed to phenylalanine. A small yield of tyrosine is obtained from the radical addition of H 2 S to ...

WebWe simulate, analyse and compare the mechanical properties of a number of molecular sheet‐like systems based on fully substituted, penta‐substituted, tetra‐substituted and tri‐substituted poly (phenylacetylene) using static force‐field based methods. WebIt has been shown that by varying the type of substitution on the phenyl ring and the length of the acetylene chain, one may be able to control the mechanical properties of the system, namely stiffness, linear compressibility and Poisson’s ratio.
