Unanticipated participation of HCl in nucleophilic chlorination reaction: Expedient route to meta chlorophenols

o-Quinone monoketals participated in a 1,4-addition reaction with HCl furnishing m-chlorophenols in high yields. Several readily available o-quinone monoketals were selected to display the generality of this serendipitous and unprecedented reaction and the results are presented herein.

Isomer specific syntheses of chlorinated catechols and guaiacols relevant to pulp bleaching

A variety of chlorinated catechols and guaiacols relevant to pulp bleaching were synthesized by employing fundamental differences in the acidities of phenolic hydroxyl groups in chlorinated catechols, and directive effects in guaiacols.

Crown Ethers from o-Quinone Diazides and Oxetane

The carbenes 11, generated by photolysis of the di- and tetrachloro-o-quinone diazides 10, react with oxetane in a 1:3 ratio to give the 15-membered crown ethers 19.In the presence of methanol, the oxonium ions 12 are trapped with formation of 1-(aryloxy)-3-methoxypropanes (13).In the absence of additional nucleophiles, 12 react with oxetane until the chain length is appropriate for inverting intramolecular attack of the aryl oxide at the α-carbon atom of the oxonium ion (18 -> 19).
