Phosphorus (III) - and Phosphorus (IV)-Substituted Alkoxyacetylenes as New Synthons in Phosphororganic Synthesis

Abstract

The diheterosubstituted acetylenes of EC=COR type, where E is Si, Ge, Sn, B, possessing an increased react-ivity both in reactions with electrophilic reagents and fragmentation processes, are extensively investigated in the Moscow University. At the same time phosphorylated alkoxyacetylenes have gained less attention. The main purpose of this work was the synthesis of previously unknown phosphorus (III)-substituted alkoxyacetylenes (I), investigation of their stability, properties and applications in phosphororganic syntheses.
