Phenyltellurinyl trifluoroacetate

The aminotellurinylation of olefins is also achieved by the treatment of olefins with phenyltellurinyl trifluoroacetate, in the presence of BF3-Et20, in acetonitrile, which acts both as a solvent and a nucleophile. ... [Pg.180]

By treatment of an alkene with phenyltellurinyl trifluoroacetate in combination with ethyl carbamate and boron trifluoride in refluxing chloroform, the addition product 5 was obtained in good yield and with complete diastereoselectivity. The stereochemistry of the product was confirmed on comparison with an authentic sample and is in agreement with the proposed mechanism. Further reduction with hydrazine gave the phenyltelluro derivative 6 in high yield, whereas heating provided the corresponding ru-oxazolidinone 725-28. [Pg.798]
