the first radical C(sp3)–H Heck-type reaction of aliphaticalcohols for selective δ- and ε-alkenol synthesis by photoredox catalysis. N-Alkoxybenzimidoyl chlorides are developed as novel alkoxyl radical precursors with tunable redox potentials. Various alkenols can be constructed by the inert C(sp3)–H Heck-type reaction of 4-cyano-N-alkoxybenzimidoyl chlorides with styrene derivatives under redox-neutral
The present invention relates to cellulose mixed esters, processes for preparing these and uses of the cellulose mixed esters, for example in coating compositions. The cellulose mixed esters have glass transition temperatures that fall within an appropriate range to allow for film formation to occur at ambient temperatures and have a total degree of substitution per anhydroglucose unit of about 2.5 to about 3.5; a residual hydroxyl functionality per anhydroglucose unit of 0 to about 0.5; a degree of substitution per anhydroglucose unit by C
