摘要:
N-Vinylformamide is purified by fractional distillation in the presence of formamide in a column under from 0.5 to 30 mbar by a method in which the distillation is controlled so that N-vinylformamide containing from 0.1 to 15% by weight of formamide is obtained as the distillate. Homopolymers having particularly high molecular weights can be prepared from the N-vinylformamide purified in this manner.
摘要:
Compositions containing an .alpha.-chloroacetanilide compound of the formula ##SPC1##Wherein R.sup.1 is selected from the group consisting of primary and secondary alkyl radicals of 1-3 carbon atoms and R.sup.2 is selected from the group consisting of hydrogen and primary and secondary alkyl radicals of 2-3 carbon atoms, are useful for protecting various agronomic crops from undesirable weed infestation. Presently preferred because of their optimum selective herbicidal activity are those compounds wherein R.sup.1 of the above structure is either methyl or ethyl and R.sup.2 is ethyl.

摘要:
Compounds having the formula ##STR1## wherein R is hydrogen, or chlorine, or alkyl having one to 4 carbons, or alkoxy having one to 3 carbons, and R.sub.1 is hydrogen, or ##STR2## or --CONH--R.sub.3, wherein R.sub.2 is hydrogen, or chlorine, or nitro, or alkoxy having no more than 3 carbons, or trifluoromethyl, and R.sub.3 is alkyl having one to 4 carbons, or cycloalkyl having no more than 6 carbons, or phenyl.The compounds are prepared by reacting R-substituted cyano-2 acetanilides with hydroxylamine to obtain compounds in which R.sub.1 is hydrogen, and then reacting with acid chlorides containing R.sub.2 or isocyanates containing R.sub.3. The compounds possess psychtropic properties.

摘要:
Trans-N-acyl-N-alkyl-1-amino-1,3-butadienes are prepared by contacting a conjugated azomethine with a strong base in an inert organic solvent at sub-zero temperature and thereafter acylating the resulting product. The trans-N-acyl-N-alkyl-1-amino-1,3-butadienes are useful as intermediates in the formation of substituted decahydro-quinolines, Pumiliotoxin C, and can also be used as the diene in Diels-Alder reactions or can be copolymerized with vinyl compounds.
