Trimethylstannyl- and Dimethylstannyl-substituted Pyrroles-Synthesis, Spectra, and Structures

Monomeric trimethylstannyl pyrroles, Me3SnR (Me=CH3 and R=-NC4H4, -NC4H2Me2-2,5, -NC4Me4-2,3,4,5, -C4H3NMe-1), are synthesized by metathesis reactions from Me3SnCl with 1(N)- and 2(C)-lithiumpyrroles, respectively. An almost similar procedure gives monomeric dimethylstannylbis(pyrroles),Me2SnR2 (1a-3a), from Me2SnCl2 and 1-Li-pyrrolides (1:2 molar ratio) in good yields. Lithiated 1,2,5-trimethylpyrrole and Me3SnCl forms the com pound Me3Sn-CH2-C4H2Me(-5)NMe (8), the reaction of Me2SnCl2 with 2-lithium-1-methylpyrrole gives oligomeric [Me2Sn-C4H2NMe-]x, (6a). The mass-, NMR, and vibrational spectra have been measured and discussed. The results of the X-ray structure determinations of Me3Sn-NC4H4 (1) and Me2Sn(-NC4Me4)2 (3a) are compared with the structure of the known dimethylmetal pyrroles of Al, Ga, and In.

The synthesis, spectroscopic characterisation, and reactivity of a series of triorganotin imidazoles, benzothiazoles and benzoxazoles R3Sn(Het) (R=Me, Bu, Ph) are described.The structure of 2-(triphenylstannyl)benzothiazole has been determined by crystallographic methods.Space group: Triclinic, P1; a 9.501(1), b 10.172(2), c 13.231(2) Angstroem, β 70.46(1), γ 69.71(1) deg, U 1082.8 Angstroem3, F(000)=484, μ(Mo-Kα) 11.74 cm-1, R=0.0719 for 2264 reflections with I>3?I.The geometry at the tin is tetrahedral.Bond angles at tin are used to discuss the reactivity and Moessbauer spectra of these species.
ZUR SYNTHESE EINIGER NEUER HETEROCYCLISCH SUBSTITUIERTER STANNANE
Jutzi, Peter,Gilge, Ullrich
, p. 163 - 168 (2007/10/02)
The in 2-position trimethylstannylated heterocycles are formed in good yields by reaction of the lithiated heterocycles benzothiazole, N-methylbenzimidazole, N-methylimidazole, N-methyltriazole, pyridine, chinoline and thiazole with trimethylchlorostannane.The thermolabile lithium compounds are synthesized by metallation or by metal-halogen exchange reactions according to known procedures.
