I ratio are general, and 2-methylpropene also gives a 3: 1 product. Terminal olefins are the most reactive with 2-methyl-1-alkenes giving faster rates than 1-alkenes. Otherwise, olefin reactivity is decreased with increased alkyl substitution of their unsaturated carbon atoms. With such tri-and tetrasubstituted olefins or 1: 1 products, acid-catalyzed isomerizations (product fluoro alcohols are acidic) occur prior to further reaction with hexafluoroacetone. ...
