Cross-Coupling Synthesis of Methylallyl Alkenes: Scope Extension and Mechanistic Study

Molecules, 2015
Cross-coupling reactions between 2-methyl-2-propen-1-ol and various boronic acids are used to obtain aromatic-(2-methylallyl) derivatives. However, deboronation or isomerization side reactions may occur for several boronic acids.
