✦ Synopsis

Abstract

1‐(2,4,6‐Trialkylphenyl)phospholes 1a,b possess a moderate aromatic character. Despite of that they underwent a sigmatropic rearrangement at 150°C to afford 2H‐phospholes 2a,b which by trapping with tolane, or in reaction with another unit of 2 gave [4 + 2] cycloadducts 3a,b, or in a reversible reaction, dimer 6, respectively. Dedimerization of species 6 at 150°C in the presence of tolane, or at 0°C under oxidative circumstances, led to 1‐phosphanorbornadiene 3a, or phosphole oxide dimer 8, respectively. © 2003 Wiley Periodicals, Inc.
