The addition of phenothiazine to phenylacetylene in super-base media proceeds regio- and stereoselectively and leads to the predominant formation of cis-10-(2-phenylvinyl)phenothiazine, which is completely converted to its trans-isomer at 200‡C. Kinetic analysis of the acidic hydrolysis of the cis- and transisomers has allowed us to assign to it an ASE2 reaction mechanism, similar to the mechanism of hydrolysis of vinyl alkyl ethers.
