Purification Methods

Purify 4-vinylbenzyl chloride by dissolving it in Et2O, washing it with 0.5% of aqueous NaOH, separating, drying the organic layer (Na2SO4), evaporating and distilling the residual oil under N2 in vacuo. Add 0.05% of 4-tert-butylcatechol as stabilizer. It is lachrymatory. [Nishikubo et al. Tetrahedron Lett 22 3872 1981, Tanimoto et al. Synth Commun 4 193 1974, Beilstein 6 IV 3818.]
