Efficient Synthesis of 2-[(Alkyltellanyl)methyl]-2,3-dihydro-1-benzofurans from Tellurium Tetrahalides and 2-Allylphenols

Efficient methods have been proposed for the synthesis of 2-[(alkyltellanyl)methyl]-2,3-dihydro-1-benzofurans in up to 90% yield through generation of (2,3-dihydro-1-benzofuran-2-yl)methanetellurolate ions from 2-[(trihalo-λ 4 -tellanyl)methyl]-2,3-dihydro-1-benzofurans and their subsequent nucleoph...
