Amphiphilic water-soluble poly(alkylarylether) dendrimers Gn (n = 1–3) with charge-neutral tetraethylene glycol monomethyl ethers at their periphery were synthesized as microreactors to control the photochemical reactions of dibenzyl ketone derivatives in aqueous solutions. Photophysical studies demonstrated that Gn can encapsulate organic molecules and provide a hydrophobic microenvironment. The

An electrochemical deoxygenative homo-coupling of aromatic aldehydes is achieved to selectively access bibenzyl and stilbene derivatives. The protocol allows the homo-coupling of aldehydes to occur after single-electron-reduction at the cathode. Taking advantage of the oxophilicity of triphenylphosphine, the electrochemicaldeoxygenation proceeds smoothly to give reductive homo-coupling products.
