Versuchsvorschrift

A mixture of 10 mmoles 2-bromopropene, 12.5 mmoles 2-methyl-3-buten-2-ol, 30 mmoles piperidine, 0.10 mmole palladium acetate and 0.20 mmole triphenylphosphine were heated together at 100° C. for 20 hrs. From the reaction mixture there was isolated an 80% yield of 2,5-dimethyl-6-piperidinohex-4-en-2-ol.
