With R2PSi(CH3)3 (R = C6H5, i-C3H7, t-C4H9) one Cl atom of 3,4-dichlor-5-methoxy-2(5 H)-furanon (1) is substituted by the R2P group. An x-ray crystal structure analysis of the phosphino derivative with R = C6H5 (2) it has shown that of the two Cl atoms in 1 only the β-position (to C= O) is substituted. The coordination chemistry of 2 and its bis- (diphenylphosphino) derivative (3) is studied by preparation of the compounds 2 · Mo(CO)5 and 3 · Mo(CO)4. With PdCl2 · 2 C6H5CN (2) gives a dinuclear complex [2 · PdCl2]2, with bridging Cl atoms. The structure is established by a comparison with the similar complex of PdCl2 and 2-chloro-diphenylphosphino-maleic acid dimethylestor, which was synthesized as a model compound and studied by x-ray crystal structure analysis.
Die Umsetzung von Diphenyltrimethylsilylarsin bzw. ‐stibin (I) mit Dichlormaleinsäureanhydrid (II) oder seinen Derivaten liefert die ditertiären Arsine (IIIa) bzw. Stibine (IIIb) und (IIIc) in kristalliner Form, die durch Elektronen‐ und IR‐Spektren charakterisiert und mit entsprechenden phosphorsubstituierten Produkten verglichen werden.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
