The reaction of N-methyl-5H,7H-dibenzo[b,g][1,5]selenazocine Se-oxide 2 with SOCl2 gave the chloroammonioselenurane 3b which was further converted into the methyl- or phenyl- substituted ammonioselenurane (4 or 5) upon treatment with Me2/

The facial diastereoselectivity in the Paterno-Buechi reaction of chiral enol ethers and benzaldehyde was studied. The substituents (RS, RL) at the stereogenic carbon atom (-C*HRSRL) attached to the β-position o

The reaction of the selenoxide 2 of N-methyl-5H,7H-dibenzo-selenazocine (1) with (CF3SO2)2O gave the selenaza dication salt 3 which acts as an oxidizing agent.A novel ?-selenurane 4 was prepared by either the reaction of selenide 1 with t-BuOCl or the reaction of selenoxide 2 with SOCl2; the crystal structure of 4 shows the chloroammonioselenurane with a distorted trigonal-bipyramidal geometry around the selenium atom.
