Synthese von 1,2,5‐Azastannaborol‐Derivaten aus Schwefeldiimid‐Anionen und cis‐Stannyl‐boryl‐alkenen – Röntgenstrukturanalyse von zwei 2,5‐Dihydro‐1‐(imino‐λ4‐sulfanyliden)‐1,2,5‐azastannaboratolen

Abstract: from the boron to the sulfur atom. Ethylene is eliminated from compound 6a (not 6b) to give the diaminosulfane derivative 7a. The 2: 1 reaction between 1 and 4 affords an unstable intermediate 8 with a fluxional structure, leading to 9 in which an EtS moiety bridges a borole ring (analogous to 6 but without the additional N -Sn coordination) and a boratole ring (analogous to 5). All compounds are characterized by 'H-, "B-, I3C-, "N-(in part), "Si-and "'Sn-NMR spectra.Organometallische Substituenten an der C = … Show more

“…The remainder are Sn(IV) compounds with a distorted tetrahedral environment. The structure of Sn(Ph) 3 (ompa) is shown in Figure 4 as an example [87a], There are several types of chomophore: SnC 4 ; SnC 3 X; SnC 2 X 2 ; SnCI 2 XY; SnCX 3 ; as can be found in [122][123][124][125][126][127][128][129][130][131][132][133][134][135][136][137], and one monodentate and a tridentate [138] giving the SnC 4 chromophore; two alkyl groups plus a hetero bidentate (C+N) ligand, methyl [169][170][171], tert-butyl [172]; two monodentate C-donors plus heterodentate (C+S or Se) [216]; two monodentate C-donors plus a chelate (N+N) [242,243], (B+B) [247], (S+S) [278][279][280][281][282][283][284][285][286][287][288], (P+P) [289][290][291], (Se+Se) [288,294]; one chelate (C+C) plus two CI atoms [260] and one tridentate (N+N+C) plus a chlorine atom [299].…”
