Include : ( 1) Allylic halogenation (using NBS + light or ROOR; using SO 2 Cl 2 + light). Allylic halogenation of a given alkene can lead to two (or more) products. In order to determine the structures of multiple products (when they occur), you have to write out the structure of the allylic radical that forms in the reaction, then look for all the possible halogenation products that can (will) form from this allylic radical (Draw either resonance structures or a dotted-line structure for the allylic radical. (2) Any S N 1reaction of an allyl halide which forms an allylic (or allyl) cation Reactions that form an allylic carbocation (solvolysis of allylic halides, reaction of allylic alcohols, etc.) can lead to two (or more) products. In order to ascertain the structures of multiple products (when they occur), you have to write out the structure of the allylic carbocation that forms in the reaction, then look for all the possible products that can (will) form from this allylic cation (Draw either resonance structures or a dotted-line structure for the allylic carbocation).
