A new strategy for the synthesis of 1,1-diaryl and triaryl-substituted alkenes was developed utilizing B(C6F5)3-catalyzed hydroarylation of alkynes with phenols. The method provided a direct route to ortho-alkenylated phenols with both terminal and internal alkynes. The reactions showed excellent regioselectivity and good stereoselectivity were observed for the hydroarylation of internal alkynes. Computational and exptl. studies suggested that for the reaction of internal alkynes and phenols, an acid-catalyzed isomerization mechanism involving two tertiary carbonium ion intermediates was responsible for the formation of Z-triaryl substituted alkenes. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Electric Literature of C13H12O2).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Electric Literature of C13H12O2
