1,3-Dipolar cycloaddition (1,3-DC) reaction of 4-ethoxy-1,1,1-trifluoro-3-buten-2-one 1 with nitrile oxides was studied. It was found that besides its C{double bond, long}C participating in the formation of isoxazole rings, trifluoromethyl activated C{dou

A series of arylnitrile oxides (6a-e) were reacted with captodative olefins (4) to yield 5-acetyl-3-arylisoxazoles.No intermediate isoxazolines were formed, the olefins thus behaved as acetylene equivalents.A plausible explanation for the observed regiose

Sealants obtained by cure of polysulfide liquid polymers with aryl bis(nitrile oxides) possess the thiohydroximic acid ester structural feature.Unexpectedly these materials were found to exhibit poor thermal stability: when heated at 60 deg they soften wi

2,4-Bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane 2,4-disulfide, 1, reacted with ketoximes at 25o followed by alkylation with methyl iodide to give oximino-4-methoxyphenyl-S-methyl-phosphonodithioate, 4. p-Tolualdehyde oxime when treated with 1 gave 2,4,6-tri-p-tolyl-1,3,5-trithiolidine, 6.The reaction of benzohydroxamoyl chlorides with 1 yielded 1,3,5,2-oxathiazaphospholes, 8, whereas p-nitrobenzohydroxamoyl chloride gave 3,6-di(4-nitrophenyl)-1,4,2,5-dioxadiazine, 11.Diarylketoximes with 1 produced 13 and 14. 9-Benzanthrone oxime with 1 afforded 9-benzanthrone thione, 16.The reaction of oximes of phenyl phenylmethylketoximes or 1,3-diphenyl-2-propanone with 1 at 80o afforded 1,3,2-thiazaphospholines, 18.
