with the DessNartin periodinane (1) in fluorotrichloromethane (freon 11). Use of the freon solvent greatly improved the recovery of this volatile aldehyde. Similarly the oxidation of 3,4-2Hz-3Z-hexen-1-ol (5) yielded 3,4-'HZ- 3Z-hexenal (6) in a 92% isolated yield with a purity of greater than 99%.
A new compound containing polyoxovanadoborate anion was synthesized and characterized by single-crystal X-ray diffraction analysis. A water molecule at the center of the anion was precisely determined. The crystals of the new compound belong to the monoclinic system, space group P2 1 /n with aοΌ1.350
