Synthesis and structure of 1-methyl-2,6-bis(electron-withdrawing group)-substituted selenabenzenes

The synthesis and structure of 1-methyl-2,6-bis(electron-withdrawing group)-substituted selenabenzenes from dihalides was presented. The monocyclic selenabenzene derivatives stabilized by two electron withdrawing groups at the 2- and 6-positions were isolated. The x-ray structural analysis of the dibenzoyl derivatives showed that the six-membered ring containing a selenium atom is planar and the structure of selenium atom is tetrahedral with four sp3 hybridized orbitals.

First isolation of selenabenzenes stabilised by two electron-withdrawing groups at the 2- And 6-positions

Selenabenzenes with two electron-withdrawing groups at 2,6-positions 9a-c were isolated and stable at room temperature and underwent the thermal rearrangement giving 2- and 4-methylselenines 13 and 14 and the oxygenation reaction giving dienone 15 and selenin-4-one 16.
