The Diels-Alder adducts 2-8: are prepared in a one-pot procedure by <2+4> cycloaddition of the perfluoro-2-arsapropene F3CAs=CF2 (1) to the corresponding 1,3-dienes, producing 1 in situ by thermal (70-80 deg C) elimination of Me3SnF from trimethylstannylbis(trifluoromethylarsane.The extreme reactivity of 1 is demonstrated by its reaction with thiophene.The observed formation of the cis and trans dimers (F3CAsCF2)2 as by-products is due to partial cycloreversion of the Diels-Alder compounds.
