The H-P bond in hydrogen phosphonates readily adds across a C=C bond [22]. Upon treatment of 1-octyne with dimethyl phosphonate in the presence of a palladium complex in refluxing tetrahydrofuran, the addition reaction proceeds smoothly to afford dimethyl l-octen-2-ylphosphonate (2) regio-and stereo-selectively (Scheme 18).

Treatment of bicyclopropylidene (1) with lithium powder led to ring opening and subsequent treatment of the reaction mixture with dimethyl sulfate afforded the methylenecyclopropane derivative 225 and 4-octyne (226) in variable ratios (Scheme 51) [143]. [Pg.130]

Ruthenacyclopentane 331 has been postulated as an intermediate in the ruthenium-catalyzed cycloisomerization of lactones <2003TL2157>. Cycloisomerization of phenylsulfonylallenes to the cyclohexane derivatives catalyzed by a ruthenium benzylidene complex might proceed through the ruthenacyclopentane intermediate 332 <2006TL3971>. The [( 7 -Cp")RuCl( -COD)]-catalyzed cyclotrimerization of 1-octyne with dimethyl acetylenedi-carboxylate proceeds via a ruthenacyclopentadiene <2004JMO(209)35>. [Pg.1289]
