摘要: The present invention relates to a process for preparing 5-methylene cyclic carbamates either by cyclization of an alkynyl amine with carbon dioxide in the presence of a copper catalyst or by forming an isocyanate from a substituted acetoacetamide followed by hydrolysis. The 5-methylene cyclic carbamates by either method are converted to 5-(chloromethylene) cyclic carbamates, using trichloroisocyanuric acid, followed by hydrolysis to a chloroketoamine.The chloroketoamine from the process of this invention additionally can be reacted with an organic acid chloride to form an amide compound which is useful as a fungicide.

摘要: A nucleophilic substitution reaction on optionally substituted dihalobenzenes is carried out in the presence of an optional catalyst followed by formation of and subsequent carboxylation of a Grignard reaction intermediate. In particular the present invention provides a process leading to optionally substituted hydroxybenzoic, alkanoyloxybenzoic, formyloxybenzoic and alkoxybenzoic acids from 1-substituted 2,6-dihalobenzenes. The invention also provides a process for the direct formation of an acyl chloride from a Grignard reagent by quenching with phosgene.

摘要: N,N-disubstituted formamides, wherein the substituents are selected to provide formamides which have low volatility, are useful as halogenation catalysts. Such catalysts are generally less hazardous to use than typical formamide halogenation catalysts because toxic catalyst by-products are also less volatile. Methods for using such catalysts are provided.
