Metliylic iodide and allylic iodide dissolved in ether and digested ^Yith sodium in sealed vessels produce itiethyl-allyl, an isomer of butylene :— rCH, ]CH' ^CHJ CH3I + + Na, Methvlic Allylic io^ae. iodide. 2NaI + CH.

By the action of ziucic ethide on allylic iodide, etliyl-allyl, isomeric 'with amylene, is 1CH3 ]CH = ^CHJ obtained:— 1CH3 ^CH 2 CH or j CH3 ^CH.,Et 1 CH, Zii]E]t2 ”1“ 2 Znl^ -h ^ch; Zincic Allylic Zincic Ethyl-aliyl. ethide. iodide. iodide. 8.
