We study the interplay between antiferromagnetism and the paramagnetic metal-insulator-transition (PMIT) on a Bethe lattice with nearest and next-nearest neighbor hopping. For t 2 =t 1 -1 the PMIT outgrows the antiferromagnetic phase and shows a scenario similar to V 2 O 3 . We also look at other or
