Versuchsvorschrift

Similarly to the procedure described in Example 1, a 17% slurry of 159 grams (5.29 moles) of paraformaldehyde in n-hexane was treated with 1488 grams (3.12 moles) of di-n-decyl dodecenyl aluminum (obtained from tri-n-decyl aluminum and acetylene). Distillation of the hydrolysis product was performed under 0.35 mm Hg. The product fraction was removed at 89°-99° C. There was obtained 133 grams (0.67 moles) of cis-2-tridecen-1-ol (13.3% of theoretical yield), having a purity of 92%. Identity of the compound was confirmed by ir and nmr spectral analyses.
