Syntheses, Structures and Reactivity of New Intramolecularly Coordinated Tin Alkoxides Based on an Enantiopure Ephedrine Derivative
2011
The syntheses of the tin compounds [LSn]2 (2), spiro-L2Sn (3), [LSnW(CO)5]2 (4), [LSnBr2]2 (5), spiro-L2Sn·SnBr4 (6) and LSn[OC(O)Ph]2 (8), where L = MeN(CH2CMe2O)[(S)-CH(Me)-(R)-CH(Ph)O], and (Ph4P)2SnBr6 (7) are reported. The compounds were characterized by elemental analysis, multinuclear NMR spectroscopy including 119Sn cross polarisation–magic angle spinning NMR (CP–MAS) (2, 3–6), electrospray ionization mass spectrometry (2–4) and single crystal X-ray diffraction analysis (2, 2·C7H8, 3a, 3b, 4·C7H8, 5, 6·C7H8, 7).

The synthesis of the intramolecularly coordinated stannylenes and their transition-metal complexes of the type RN(CH2CMe2O)2SnL [1: L = lone pair, R = Me; 2: L = lone pair, R = n-octyl; 5: L =W(CO)5, R = Me; 6: L = Cr(CO)5, R = Me; 7: L =W(CO)5, R = n-octyl; 8: L = Fe(CO)4, R = Me], and of the tin(IV) compounds RN(CH2CMe2O)2SnBr2 (9: R = Me), [MeN(CH2CMe2O)2SnBr2]2·SnBr2(OH)2 (10) and spiro-[RN(CH2CMe2O)2]2Sn (3: R = Me; 4: R = n-octyl) is reported. The compounds were characterized by elemental analyses, 1H, 13C, 119Sn, and 119Sn magic-angle spinning (5, 6) NMR spectroscopy, electrospray mass spectrometry, and single-crystal X-ray diffraction analysis.
