WebTransformation by methylating agents was decreased by 3-aminobenzamide, whereas transformation by ethylating agents was increased. These results confirm earlier work on transformation by methylating agents, X-rays and u.v. light. Transformation by ethylating agents, however, appears to proceed by a different mechanism.

The formal "alkyl anion" attacks an electrophile, forming a new covalent bond between the alkyl group and the electrophile. The counterion, which is a cation such as lithium, can be removed and washed away in the work-up. Examples include the use of organometallic compounds such as Grignard (organomagnes… ont types bt
