WebDimethyl sulphate breaks the oh bond and forms anisole. ... Those methyl groups are readily attacked by nucleophiles because of the great induction effect caused by the neighbor atoms which are much more electronegative than the carbon atom, which makes those more positively charged.
WebAnisole is also known as methyl phenyl ether or methoxy benzene. Phenetole is also known as ethyl phenyl ether or ethoxy benzene. Anisole and phenetole are unaffected by most of the acids and alkalis. Anisole. Anisole is a colorless liquid with an anise seed scent, and many of its derivatives can be found in natural and synthetic scents. WebWe investigated the hydrolysis of anisole to phenol in high-temperature water with and without water-tolerant Lewis acid catalysis. With no catalyst present, anisole hydrolyzes to phenol in 97% yield after 24 hours at 365 °C, our experimentally determined optimal temperature and time. Experiments with varied water density and analysis of ...
