Group 16 oxides reaction with, phosgene

A series of reactions with gases have been selected for the rapid quantification of many of the major products from the oxidation of polyolefins. Infrared spectroscopy is used to measure absorptions after gas treatments. The gases used and the groups quantified include phosgene to convert alcohols and hydroperoxides to chloroformates, diazomethane to convert acids and peracids to their respective methyl esters, sulfur tetrafluoride to convert acids to acid fluorides and nitric oxide to convert alcohols and hydroperoxides to nitrites and nitrates respectively.

Azine approach. DCC dehydration of the 3-oxoquinazoline-4-hydroxamic acid (602) gives an isocyanate (603) via a Lossen rearrangement addition of the AT-oxide oxygen to the isocyanate group effects the cyclization. The same product is formed by the phosgene reaction with 4-amino-2-methylquinazoline 3-oxide (76TL3615). [Pg.724]
