cze	aminostannany a aminostannyleny obsahující C,Nchelatující ligand	Aminocínaté a cíničité sloučeniny {[(2,6-i-Pr-C6H3)(H) N]-mu-(Sn)-Cl}(2), {2-[(CH3)(2)NCH2]C6H4}(2)Sn[N(H) (2,6-i-Pr-C6H3)](2) a {2-[(CH3)(2)NCH2]C6H4}Sn[N(2,6-i-Pr-C6H3)(SiMe3)] byly připraveny eliminací halogenidem litným z cíničitých halogenidů za vzniku odpovídajících litných komplexů. [(2,6-i-Pr-C6H3)(H) N] Li (1) reaguje s polovinou molárního ekvivalentu SnCl2 za vzniku {[(2,6-i-Pr-C6H3)(H) N]-mu(Sn)-Cl}(2). Stejný amid lithný (1) poskytuje s R3SnCl odpovídající aminostannany. Další reakce těchto sloučenin s n-butyllithiem poskytuje výchozí 1 a tetraorganostannany. {2-[(CH3)(2)NCH2] C6H4}(2)SnBr2 reaguje se dvěma ekvivaleny 1 na {2-[(CH3)(2)NCH2]C6H4}(2)Sn[N(H)(2,6-i-Pr-C6H3)](2). Dimerní heteroleptický stannylen {[(2,6-i-Pr-C6H3)(SiMe3)N](mu(2)-Cl)Sn}(2) reaguje s 2-[(CH3)(2)NCH2] C6H4Li na monomerní {2-[(CH3)(2)NCH2]C6H4}Sn[N(2,6-i-Pr-C6H3)(SiMe3)].	cínaté a cíničité sloučeniny;amino skupina;C,Nchelatující ligand;DFT kalkulace
eng	Aminostannanes and Asminostannylenes Containing a C,N-chelated Ligand	Aminotin(II and IV) compounds {[(2,6-i-Pr-C6H3)(H) N]-mu-(Sn)-Cl}(2), {2-[(CH3)(2)NCH2]C6H4}(2)Sn[N(H) (2,6-i-Pr-C6H3)](2) and {2-[(CH3)(2)NCH2]C6H4}Sn[N(2,6-i-Pr-C6H3)(SiMe3)] were prepared by lithium halide elimination from tin halides and corresponding lithium complexes. [(2,6-i-Pr-C6H3)(H) N] Li (1) reacts with one half of molar equivalent of SnCl2 to give {[(2,6-i-Pr-C6H3)(H) N]-mu(Sn)-Cl}(2). The same lithium amide (1) gave with R3SnCl corresponding aminostannanes. Further reactions of these compounds with n-butyllithium gave the starting 1 and tetraorganostannanes. {2-[(CH3)(2)NCH2] C6H4}(2)SnBr2 reacts with two equivalents of 1 to {2-[(CH3)(2)NCH2]C6H4}(2)Sn[N(H)(2,6-i-Pr-C6H3)](2). The dimeric heteroleptic stannylene {[(2,6-i-Pr-C6H3)(SiMe3)N](mu(2)-Cl)Sn}(2) reacts with 2-[(CH3)(2)NCH2] C6H4Li to the monomeric {2-[(CH3)(2)NCH2]C6H4}Sn[N(2,6-i-Pr-C6H3)(SiMe3)].
