Rapid and stereoselective Diels-Alder reactions can be run in ethanol or methy- lene chloride in the presence of FelI1-doped K10 montmorillonite. ## IMPRESSIVE improvements of the Diels-Alder reaction have been achieved recently.
Aluminium (III) tetraphenyl porphyrin chloride (AITPPCI) has been shown to catalyze Diels-Alder reactions of a&unsaturated carbonyl.compounds in moderate yield. Wdivity based on electronic effects is exhibited which is different from that seen with catalysts such as diethylaluminium chloride.
