Evidence for this mechanism is as follows: The addition of pyridine to the mixture of alcohol and thionyl chloride results in the formation of alkyl halide withinvertedconfiguration. Inversion results because the pyridine reacts with ROSOCl to give ROSONC5H5before anything further can take place. Th...

Alcohol derivatives can also be alkylated to yield ethers derivatives: for example, using analkyl halide(the Williamson ether synthesis) ROH+R1X → ROR1 Alcohols are also good alkylating agents in the presence of suitable acid catalysts. For example, most methyl amines are prepared by alkylation ...

Formation of cyclopropylamines and cyclopropanols fromalkylmagnesium halidesand esters, amides, or nitriles, catalyzed by titanium alcoholates, was discovered by Kulinkovich in 1989. The reaction mechanism includes the formation of dialkoxytitanacyclopropanes, which reacts with a carbonyl compound or a...
