Tellurium in the ''No-Solvent'' organic synthesis of allylic alcohols

[摘要] Elemental tellurium can be reduced by rongalite (HOCH2SO2Na . 2H(2)O)-KOH in the solid phase by application of ultrasound or by microwave irradiation. Without solvent, the organic substrate (eg sulfonate ester of an oxiranemethanol) is added with further sonication or irradiation to yield the desired organic product (eg allylic alcohols) and elemental Te which may be recycled. Phase-transfer conditions (water-toluene) also ate satisfactory. (C) 1997 Elsevier Science Ltd.
