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.

Unlocking the Accessibility of Alkyl Radicals from Boronic Acids through Hydrogen-bond Assisted Organophotoredox Activation [PDF]
, 2021 Despite their prevalence in organic synthesis, the application of boronic acids (BAs) as alkyl radical precursors in visible-light assisted photocatalyzed reactions has been limited by their high oxidation potential.

Highly Diastereo- and Enantioselective Allylboration of Aldehydes using alpha-Substituted Allyl/Crotyl Pinacol Boronic Esters via in Situ Generated Borinic Esters [PDF]
, 2013 Readily available, alpha-substituted allyl/crotyl pinacol boronic esters often give low E/Z selectivity (with Z favored) in reactions with aldehydes. We found that addition of nBuLi to the pinacol boronic ester followed by trapping of the alkoxide with ...

(2-Butoxyphenyl)boronic acid [PDF]
Acta Crystallographica Section E Structure Reports Online, 2008 The title compound, 2-(CH(3)CH(2)CH(2)CH(2)O)C(6)H(4)B(OH)(2), exists as a centrosymmetric hydrogen-bonded dimer. Dimers are linked via C-H⋯π and π-π [with closest C⋯C contact of 3.540 (3) Å] inter-actions to produce a two-dimensional array.
