Access to Hydroxy-Functionalized Polypropylene through Coordination Polymerization

Preparation of polyethylenes containing hydroxy groups has been already industrialized through radical copolymerization under harsh conditions followed by alcoholysis. By contrast, hydroxy-functionalized polypropylene has proven a rather challenging goal

Regioselective Arene and Heteroarene Functionalization: N-Alkenoxypyridinium Salts as Electrophilic Alkylating Agents for the Synthesis of α-Aryl/α-Heteroaryl Ketones

A direct regioselective functionalization of arenes and heteroarenes using N-alkenoxypyridinium salts as electrophilic alkylating agents for the synthesis of α-aryl/heteroaryl ketones has been developed. The method generates alkylating agents from alkynes and N-pyridine oxide followed by site-selective electrophilic substitution with a broad range of arenes and heteroarenes including benzene derivates, phenols, ethers, indoles, pyrroles, furans, and thiophenes in one pot. Kinetic isotope effect measurements and DFT studies reveal that this reaction likely proceeds through a carbon-cation intermediate.

Improved Synthesis of C2 and C6 Monoderivatives of α- And β-Cyclodextrin via the Click Chemistry Approach

An efficient multigram-scale azide-alkyne coupling of cyclodextrin derivatives mono-6-azido-6-deoxy-β-cyclodextrin, mono-2-O-propargyl-β-cyclodextrin, and mono-2-O-propargyl-α-cyclodextrin with terminal alkynyl aryl ethers or azides, mediated by copper(I) is reported. This process uses a stoichiometric ratio of substrates and 5 mol% of the copper catalyst to give the products with full conversion; thus, no chromatographic purification is necessary. The yields of both α- and β-cyclodextrin derivatives are in the range of 80 to 99%.
