Previously one of us reported 121 that methyl 3,4-0-isopropylidene-2-Omethanesulfonyl-5.thio-~-D-~~pyranoside (1) readily unde~ent ring ~ntra~tion in methanol to give 2,5-dideo~-2,5-epithio-o-arabinose dimethyl acetal (2). It was of interest to examine this reaction with the corresponding D-arabinos
**A contribution to the structural chemistry of compounds of type A~2~B~2~** (A = S, Se; B = F, Cl, Br) is provided by the X‐ray structure analysis of β‐SeBr at −80°C. The BrSeSeBr molecules (SeSe = 2.241 Å; dihedral angle 93.58°) are arranged in the crystal in such a manner that some of the Se…Br
