Dibromobis(phosphine)palladium(II) complexes, PdBr2(L)(2) [L: PPh3, P(
p-Tol)(3)], react with cyclohexane and an alcoholic solution of sodium
alkoxide, NaOR (R = Me, Et, Pr-i), at 30-60 degrees C affording the c
orresponding alkyl cyclohex-1-enyl ethers, ROC6H9, in 30-140% yield on
palladium both under argon and under air; benzene is inert under the
reaction conditions, sodium tert-butoxide does not enter the hydrocarb
on alkoxylation.
