Synthesis of 1-benzoxepines by dehydrochlorination of carbene adducts of chromenes has been carried out. Different alkyl-, alkylidene-, alkoxy-, aryl- and hetaryl- substituted 1-benzoxepines were obtained. The PMR spectra were run on a Tesla BS-487 spectrometer (80 MHz), using HMDS as internal standard; solvent - CCl/sub 4/ (for compound VIIIb, CH/sub 2/Cl/sub 2/ was used as solvent). The IR spectra were recorded on a Specord IR-71 spectrophotometer in mineral oil, using NaCl prism. The UV spectra were obtained on a Specord UV-vis spectrophotometer, and the mass spectra on a MS-30 spectrometer.
