Abstract
en = N,N,N',N'-tetramethylethylenediamine;L = dimethylbis(4-pyridyl)silane (dmps), methylvinylbis(4-pyridyl)silane (mvps)) have been synthesized, andtheir structures have been characterized by X-ray single crystallography. The skeletal structures consist of one20-membered metallamacrocycle, two 5-membered metallacycles, and four pyridyl groups. The local geometryaround the palladium(II) ion approximates to a typical square planar arrangement with four nitrogen donors.Delicate difference in catalytic effects on hydrogenation was investigated based on the structure of catalyst andsubstrates.Key Words : Dimethylbis(4-pyridyl)silane, Hydrogenation catalysis, Metallacyclodimer, Methylvinylbis(4-pyridyl)silane, Palladium(II) complexesIntroductionVarious metallamacrocyclic compounds have been syn-thesized and characterized for functional supramolecularmaterials that can be utilized for molecular machines,switches, recognition,selective transformation, drug deliverysystems, biomimetics, storage, and catalysts.
