Abstract

1997 organo-phosphorus compounds, nonmetal heterocycles organo-phosphorus compounds, nonmetal heterocycles S 0087 37 -200 1-(2,4,6-Tri-tert-butylphenyl)-3-methylphosphole: A Phosphole with a Significantly Flattened Phosphorus Pyramid Having Pronounced Characteristics of Aromaticity. -The title compound (V) is synthesized to test the effect of the strongly sterically demanding P-substituent on the geometry of the molecule. The phosphole ring, normally resistant to electrophilic substitutions, is found to react with AcCl/AlCl3 showing a considerable cyclic electron delocalization. -(KEGLEVICH, G.; BOECSKEI, Z.; KESERUE, G.
