This invention relates to the reaction of an alcohol and a compound having the general formula: H RC-C ---X A HCR' H in which R and R' are selected from the group consisting of hydrogen and alkyl radicals and X is a halogen.10 More specifically, the invention is directed to the man...
Reaction of alcohol 21 with benzothioamide proceeds smoothly to give thiazole 23 as a single product. However, in the case of secondary propargylic alcohol 24, a 29 : 71 mixture of thiazoles 30 and 31 is obtained in 87% overall yield. Presumably, both the instability of the allenyl cation...
Alkyl Halide reactivity In the modern usage of the Finkelstein reaction, it has expanded including in the process of changing alcohols to alkyl halides by converting the alcohol to a sulfonate ester in the first stage, and then the substitution changes. ...
