  • Methylidenecycloproparenes: Novel Compounds with Fascinating Properties
    作者:Brian Halton、Peter Stang
    DOI:10.1055/s-1997-723
    日期:1997.2
    Proton abstraction from the methylene position of a cycloproparene provides the corresponding C1 anion that can be intercepted by a carbonyl-containing compound to provide a wide range of novel methylidenecycloproparenes. The physical and chemical aspects of this comparatively new class of surprisingly stable, strained compounds have been explored. The present account provides a perspective on these developments from the initial experiments in the Utah laboratories.
    从环丙烯环的甲叉位质子抽象化生成的相应C1阴离子,能够被含羰基的化合物捕获,从而获得广泛的、新型的亚甲基环丙烯类化合物。人们已经探讨了这类相对较新的、出乎意料的稳定性大、张力高的化合物的物理和化学性质。本文从犹他实验室最初的实验研究简述了这些进展。
  • Studies in the cycloproparene series: oxygen-containing 1H-cyclopropa[b]naphthalenes and their methylidene derivatives

    3,6-Dimethoxy-1H- cyclopropa[b]naphthalene 4 is available from 1,4-benzoquinone in four steps in 27–28% overall yield. The diether 4 provides a range of methylidene derivatives 15a–e by way of the disilyl compound 14, and is efficiently demethylated by cerium(IV) ammonium nitrate to provide 1H-cyclopropa[b]naphthalene-3,6-dione 16 (85%) whose crystal structure is reported. Quinone 16 is the first stable

    A new type of palladium(0) complex, (5,8-dihydro-1,4-naphthoquinone)Pd(PPh3)2 and (5,8,9,10-tetrahydro-1,4-naphthoquinone)Pd(PPh3)2, having both olefin and quinone or dihydro-quinone sites in a ligand molecule was prepared. IR and 1H NMR spectroscopic studies of these complexes suggested that it is the quinone or dihydro-quinone CC bond which is complexed to Pd. Ligand exchange reactions showed that
