AbstractThe uncatalyzed silylphosphanylation of acetylenic N-trifluoromethylsulfonyl-carboxamides by Ph2P–SiMe3, formally an insertion of a C,C triple bond into a P–Si bond, is reported. Some characteristic functional group transformations of the resulting 3-PPh2-2-SiMe3-N-triflyl-acrylamides were briefly explored: transamidation of the N-triflylamide group with allylamine, P oxidation and protodesilylation. A hydrophosphorylation of the acetylenic triple bond with chloro(diphenyl)phosphane is also reported.

New Entry

The synthesis, crystal structure, and characterization of a silicon-silicon triply bonded species, disilyne with two bis[bis(trimethylsilyl)methyl]isopropylsilyl substituents, are described. The nature of the sp-hybridized silicon atoms is discussed from the viewpoint of spectroscopic results and theoretical calculations. The reactivity of the disilyne with alkali metals, tBuLi, and π-bonded compounds such as cis- and trans-2-butenes and phenylacetylene is also described.

Radical Cascade

A metal- and catalyst-free photoinduced radical cascade hydroalkylation of 1,7-enynes has been disclosed. The process is triggered by a SET event involving a photoexcited electron-donor-aceptor complex between NHPI ester and Hantzsch ester, which decomposes to afford a tertiary radical that is readily trapped by the enyne. <a>The method provides an operationally simple, robust and step-economical approach to the construction of diversely functionalized dihydroquinolinones bearing quaternary-centers. A sequential one-pot hydroalkylation-isomerization approach is also allowed giving access to a family of quinolinones. A wide substrate scope and high functional group tolerance was observed in both approaches</a>.
