An unexpected synthetic approach to polysubstituted olefins through the scandium(III) trifluoromethanesulfonate catalyzed ring-opening reaction of donor–acceptor cyclopropanes with 1,1-diphenylethanols was developed. The reactions, which are experimentally easy to handle, feature tolerance of various functional groups and mild reaction conditions. On the basis of experimental evidence, a plausible mechanism was also proposed.

An operationally simple iron-catalyzed reductive cross-coupling reaction between aryl halides and allyl electrophiles has been developed. The underlying domino process exhibits high versatility with respect to the allylic leaving group (acetate, tosylate, diethyl phosphate, methyl carbonate, trimethylsilanolate, methanethiolate, chloride, bromide) and high economic and environmental sustainability with respect to the catalyst system (0.2-5 mol% tris(acetylacetonato)iron(III), ligand-free) and reaction conditions (tetrahydrofuran, 0°C, 45 min).

Three α,α,ω,ω-tetraaryl α,ω-diols 10 were synthesized via Grignard reactions of p-tert-butylbromobenzene with 1,10-bis(p-carbethoxyphenoxy)decane, dimethyl terephthalate, and dimethyl adipate (8).The diols 10 were converted to 1,10-bisp-bis(p'-tert-buty

Several bulky monomers for polyrotaxanes, including α,α,ω,ω-tetraarylmethyl bisphenol 9, diethyl di(p-t-butylbenzyl)malonate (10), and 1,1-di(p-t-butylphenyl)ethene (12), were synthesized.All the intermediates (8, 11) and final products (9, 10, and 12) ar
