摘要：

The novel dialkyltin 2,3-bis(diphenylphosphino)maleic acid adducts (R2Sn)(O,O'-dpmaa) [1a, R = Me; 1b, R = Bu; dpmaa = bis(diphenylphosphino)maleic acid] were synthesised from dpmaa and R2SnCl2 n or Bu2SnO. They were fully characterised by elemental analysis, IR- and multinuclear NMR-spectroscopies as well as X-ray crystallography [in the case of la as its Ph2P(O)(CH2)(2)P(O)Ph-2 adduct]. Both were found to be cyclic trimers in the solid state that dissolve in the case of 1b into an equilibrium mixture of oligomers. (c) 2005 Elsevier B.V. All rights reserved.
