18 - 167A Simple Route to Kinetically Unstabilized Phosphaalkynes. —Title compounds (III) are prepared by a two-step sequence involving thechemoselective reduction of phosphonates (I) by prior prepared dichloroalane,followed by elimination of HCl from phosphines (II) under treatment with strongLewis base DBU. The purification methods to obtain crude isolated products(III) from the reaction mixtures are reported in detail. — (GUILLEMIN,JEAN-CLAUDE; JANATI, TAJDINE; DENIS, JEAN-MARC; J. Org.
