A Comparative 19F NMR study of electronic effects in some fluoroaryl compounds of antimony and bismuth and in their carbon and nitrogen analogues

SnCl4‐Induced Unsymmetrical Cleavage of Bis(N,N‐diethylcarbamoyltelluro)‐arylmethanes: Generation of Tellurobenzaldehydes

“…In addition, treatment of 5e (R 2 = p ‐FC 6 H 4 ) with SnCl 4 (1.5 mol) in benzene at R.T. afforded an unexpected triarylmethane 9e (R 2 = p ‐FC 6 H 4 ) in 12% yield besides a complex mixture. Furthermore, the similar reaction of 5e with SnCl 4 carried out in CH 2 Cl 2 in the presence of an excess amount of allyltrimethylsilane at –78°C afforded unstable Te ‐allyl N,N ‐diethyltellurocarbamate ( 10 ) in 12% yield besides several uncharacterized products.…”
