Darstellung und Struktur neuer sechsgliedriger Metallaheterocyclen – Insertion von Platin in Selen-Stickstoff- und Schwefel-Stickstoff-Bindungen

TLDR: The reaction of 1,2,5-selenadiazoles 2 and 4 and the bicycle 6 with (η2-ethene)bis(triphenylphosphane)platinum(0) leads to the cyclic coordination compounds (Ph3P)2PtSeN2(CR)2 (R = CN, 3; R = OCH2CF3, 5) and dem Bicyclus (Ph 3P) 2PtC4Cl2N4S3 (7) as discussed by the authors.

Abstract: Die Reaktion der 1,2,5-Selenadiazole 2 und 4 sowie des Bicyclus 6 mit (η2-Ethen)bis(triphenylphosphan)platin(0) fuhrt zu den cyclischen Koordinationsverbindungen (Ph3P)2-PtSeN2(CR)2 (R = CN, 3; R = OCH2CF3, 5) und dem Bicyclus (Ph3P)2PtC4Cl2N4S3 (7). Von 3 wurde eine Rontgenstrukturanalyse angefertigt, die das Vorliegen eines sechsgliedrigen Ringes bestatigt. Preparation and Structure of New Six-membered Metallaheterocycles – Insertion of Platinum in Selenium-Nitrogen and Sulfur-Nitrogen Bonds The reaction of 1,2,5-selenadiazoles 2 and 4 and the bicycle 6 with (η2-ethene)bis(triphenylphosphane)platinum(0) leads to the cyclic coordination compounds (Ph3P)2PtSeN2(CR)2 (R = CN, 3; R = OCH2CF3, 5) and the bicycle (Ph3P)2PtC4Cl2N4S3 (7). The structure of 3 was determined by an X-ray structure analysis.
