<p>One facile and efficient strategy for the hydrosilylation of steric 1,1-disubstituted
terminal alkenes is demonstrated. Investigations on substrate scope and control
experiments revealed the necessity of thioether in promoting this process under
a simple iridium catalysis system. This convenient and feasible method is
expected to be useful in the synthesis of sulfur-containing organosilicon
polymers with different side-chains.</p><p><br></p>

Maltodextrins have an increasing number of biomedical and industrial applications due to
their attractive physicochemical properties such as biodegradability and biocompatibility. Herein, we
describe the development of a synthetic pathway and characterization of thiol-responsive maltodextrin
conjugates with dithiomaleimide linkages. 19F NMR studies were also conducted to demonstrate the
exchange dynamics of the dithiomaleimide-functionalized sugar end groups.
Abstract Polymethine oxonols show temperature dependent 1H-NMR-spectra because of restricted rotation of the end groups. The dependence of the value of the corresponding free enthalpy of activation AGt on the length of the poly-methine chain can be explained by the change of the π-electron contribution to ⊿G≠.
