Dibutyl telluride assists cyclopropanation of α,β-unsaturated ketone, ester, and nitrile with dibromomalonic esters without solvent at room temperature. In addition, it effects alkylidenation of aldehydes including α,β-unsaturated aldehyde with the same reagent.
在室温下,二丁基碲化物有助于 α,β-不饱和酮、酯和腈与二溴丙二酸酯的环丙烷化反应。此外,它还可以用相同的试剂进行醛的烷基化,包括α,β-不饱和醛。
