Abstract Barbiturates substituted at the 5-position with organyltelluroalkyl or organylselenoalkyl groups were prepared by ring annulation of appropriately substituted diethyl malonates with urea or thiourea. The substituted diethyl malonates [phenyl- tellurobutyl (ethyl), i-propyltelluropropyl (ethyl), i-propyltelluropropyl (allyl), i- propylselenopropyl (ethyl), and phenylselenohexyl (methyl) were prepared in 55–91% ...
