Similarly to the procedure described in Example 1, a 25% slurry of 144 grams (4.80 moles) of paraformaldehyde in n-hexane was treated with 1083 grams (4.59 moles) of di-n-octyl decenyl aluminum (prepared from tri-n-octyl aluminum and acetylene). Distillation of the hydrolysis product was performed under 2 mm Hg. The product fraction was removed at 85°-95° C. There was obtained 210 grams (1.25 moles) of cis-2-undecen-1-ol (27.2% of theoretical yield), having a purity of 91%. Identity of the compound was confirmed by ir and nmr spectral analyses.
