Özet:

 

Organotin carboxylates of general formula R3SnL (1), (2),  (4) and (6), R2SnL2 (5) and {[(R2SnL)2O]2} (3), where L =  N-maleoylglycinate, N-maleoyl-b-alaninate and N-maleoylmethioninate,  were prepared.  The synthesis of these compounds was achieved by  either reaction of organotin halides, R3SnCl, with triethylammonium  salt of N-maleoylamino acids or/and organotin oxides, (R3Sn)2O and  R2SnO, with maleamic acid in the presence of triethyl amine.  These  compounds were characterized by FT-IR, multinuclear NMR (1H, 13C  and 119Sn), mass and 119mSn Mössbauer spectroscopy.  The  geometry around the tin atom is compared both in solution and in solid  state.  Different literature methods were employed to calculate the  C-Sn-C angle in non-coordinating solvents.  The mass fragmentation  pattern demonstrated the McLafferty rearrangement in compound (6).   Salient features of the X-ray structures for (1), (4) and (6) are also  given.
