Use of C,N-chelated triorganotin(IV) fluoride for fluorination of organic compounds, coordination compounds, phosphines, silanes and stannanes

Abstract

C,N-chelated triorganotin(IV) compounds containing the L CN ligand, where L CN is {2-[(CH 3 ) 2 NCH 2 ]C 6 H 4 } -, reveal the monomeric structure in solution as well as in the solid state with pentacoordinated tin atom in trigonal bipyramidal coordination polyhedra. These compounds were used as mild and very effi cient metathetical fl uorinating agents in fl uorinations of various organic, inorganic substrates and organometallic species containing E-Cl (E = C, Si, P, S and metal) bond(s) (metal halides, phosphines, silanes, etc.) as well as the F ion selective carriers with low detection limits.

Novel Tin-Containing Crown Ether Substituted Ferrocenophanes as Redox-Active Hosts for the Ditopic Complexation of Lithium Chloride

“…An interesting formal analogy can be drawn between [ 3 ·LiCl] and the zwitterionic 2-( N , N -dimethylammoniomethyl)phenyl-containing triorganodichloridostannate 2-Me 2 HNCH 2 C 6 H 4 SnCl 2 Ph 2 and related derivatives . In the latter compound, a proton is coordinated by the amine nitrogen atom (Lewis base) and a chloride anion is coordinated to a tin atom (Lewis acid).…”
