Abstract
The solid-state thermolysis of a sterically hindered Delta(3)-1,3,4-te lluradiazoline 2 afforded products resulting from intermediary tellone 1 and diazo compound 8 formed by retrocyclization, whereas the flash vacuum thermolysis of 2 led to isolation of tellone 1 as green needles . The spontaneous dimerization of 1 thus obtained occurred in the soli d state to give the corresponding 1,3-ditelluretane 10, which underwen t the thermal cycloreversion in solution to regenerate pure tellone 1.
