Abstract

^1^H, ^13^C and ^77^Se chemical shifts of sulphur and selenium analogues of furocoumarin are given. These data are very similar to the values obtained from benzofuran, coumarin and their sulphur and selenium analogues.

The possible tautomeric equilibria of benzofuroxan and its sulphur and selenium analogues were examined by multinuclear NMR methods. The 1 H, 13 C, 14 N and 15 N NMR signal assignments were achieved largely by 2D methods and some older nitrogen NMR data were verified. At room temperature and above,
