—— | 3-methyl-1,4-benzodioxin-2-methanol | 142532-63-6 | C10H10O3 | 178.188 |
The application of known methodology has provided 2,3-dimethylidene-2,3-dihydro-1,4-benzodioxin (12) as the essential precursor for preparation of the cyclopropa-fused dibenzodioxin 3,8-dioxa-1H-cyclopropa [b] anthracene (14). Cycloproparene (14) is both unstable and acid-sensitive, and readily dimerizes to a mixture of the dihydrotetraoxaheptacene (15) and its heptaphene analogue (16).
