2-(Alkenyloxymethyl)-2-propenylzinc bromides 2a-e and 2-(allylmethylaminomethyl)-2-propenylzinc (or magnesium) halides 2g rearrange thermally to 5-(1-bromozincalkyl)-3-methyleneoxacycloalkanes 1a-e and 5-(bromozinc(or chloromagnesium)methyl)-3-methylene-N-methylpiperidine 1g; some of the former can be isomerized by Pd(PPh3)4 to methylenecyclopentanes 3.
