Burning an ethanolic solution of vanadyl(IV) acetylacetonate in a glass beaker affords monoclinic VO 2 [VO 2 (M)], and thus brings this formerly expensive oxide into the realm of conventional laboratory synthesis. Differential scanning calorimetry (DSC) showed consistent heating and cooling curves (see picture) for 50 reversible transitions between VO 2 (M) and the higher‐temperature rutile phase of VO 2 .
