Small-Ring Compounds. XXVIII. Isotope-Position Rearrangements of Allylcarbinyl Grignard Reagents

Abstract

We have observed a remarkable rearrangement while attempting to prepare 4-penten-2-ylarnine (I) through the reaction of the Grignard reagent derived from 4-penten-2-yl chloride (II) with methoxylamine, in that part of the amine formed appeared to be 2-methyl-3-butenylamine (III)
