adhesive materials, 3,4-dihydroxyphenyl groups were introduced for the first time into syndiotactic polybutadiene (1,2-unit content >90%). Two ways of introduction were studied: cross metathesis and thiol—ene addition. Eugenol, an available product of plant origin, was used as a source of 3,4-dihydroxyphenyl groups following the protection of its oxygen-containing groups with Et3SiH in the presence of B(C6F5)3)

The untapped potential of radical thiol‐yne mono‐additionchemistry is exploited to overcome the known limitations of thiol‐ene chemistry in polymer coupling and block copolymer formation. By careful choice of alkyne, the reaction can selectively lead to the mono‐additionproduct with efficiencies surpassing those achieved by traditional thiol‐ene chemistry. This improvement is illustrated by the nearly

reported. Silyl protection is shown to be critical for the oxidative stability of catecholic moieties during synthesis and processing, which allows functionalized polysiloxane derivatives to be fabricated into 3D microstructures as well as 2D patterned surfaces. Deprotection gives stable catechol surfaces whose adhesion to a variety of oxide surfaces can be precisely tuned by the level of catechol incorporation
