Abstract: A visible-light-induced intramolecular α-alkenylation has been developed via metal-free dehydrohalogenative C(sp2)-C(sp2) coupling reaction to afford seven- and eight-membered rings. Extensive mechanistic studies prove that this reaction proceeds through a [2 + 2]-photocycloaddition, elimination, and retro-[2… read more here.

Abstract: Spin-crossover (SCO) materials with multiple spin states have attracted special interest for their potential applications in multi-switches and high-order data storage. Herein, an unprecedented asymmetric seven-/eight-step SCO behavior is revealed in a three-dimensional Hofmann-type metal–organic… read more here.

Abstract: Abstract Diphenyl N-dimethylamidophosphate, O = P(OPh)2(NMe2), was introduced in the coordination sphere of trivalent lanthanide ions in combination with β-diketonates to obtain seven- and eight-coordinate complexes, [Ln(β-dike)3{O = P(OPh)2(NMe2)}n] (Ln = Eu, β-dike = dibenzoylmethanate, n = 1; Ln = Eu, β-dike = tenoyltrifluoroacetonate, n = 2; Ln = Tb, β-dike = acetylacetonate, n = 2).… read more here.
