Abstract The addition of the pseudohalogens nitryl iodide (NO2I), iodine nitrate (IONO2), and iodineazide (IN3) to the terminal, unsaturated sugar, methyl 5,6-dideoxy-2,3-di-O-p-tolylsulfonyl-α- l -arabino-hex-5-enofuranoside (1), is described. On treatment with iodine in ether solution, tri-O-acetyl- d -glucal dimerizes to yield the two anomers of 1,3,4,6-tetra-O-acetyl-2-deoxy-2-C-(4,6-di-O-acetyl-2
