Mechanism, catalysis and predictions of 1,3,2-diazaphospholenes: theoretical insight into highly polarized P–X bonds

1,3,2-Diazaphospholene-based compounds 2 with two electron donor amino groups on the heterocyclic skeleton, featuring an extremely polarized and weak P–X bond (X = H, CCMe, NMe₂, PMe₂ and SMe), are predicted to have a useful catalytic ability.
