One-pot synthesis of aryl butyl tellurides from tellurium tetrachloride and activated aromatics through a solventless step
摘要:
A solventless preparation of aryl tellurium trichlorides from activated aromatic compounds avoiding the use of hazardous solvents as carbon tetrachloride and chloroform is described. The trichlorides were reduced and alkylated leading to aryl butyl tellurides in a one-pot procedure. Transmetallation of these tellurides with n-butyllithium followed by reaction with benzaldehyde gave the corresponding benzhydrols in good yields. (C) 2004 Elsevier B.V. All rights reserved.

The ring opening reaction of N-tosyl aziridines with dilithium arylthienylcyanocuprates generated from arylbutyltellurides produced phenethylamine derivatives in good to excellent yields.
