## Abstract An improved sonochemical procedure for the synthesis of dimethyl [6]paracyclophaneβ8,9βdicarboxylate (2a) on a 10βg scale is described. The title compound 2d was synthesized from 2a in three steps. Irradiation of 2d yielded the Dewar isomer 3. In solution, the reaction enthalpy for the

Both the composition and structure of A 1Γx Sn 9Γx Bi 11+x Se 26 (A=K, Rb, Cs) were predicted on the basis of the homologous series A m [M 6 Se 8 ] m [M 5+n Se 9+n ] (M=Sn, Bi) and targeted for synthesis. A 1Γx Sn 9Γx Bi 11+x Se 26 adopts a new structure type that fits the structural evolution of th
