Donor-acceptor-substituted cyclopropanes: Versatile building blocks in organic synthesis,, certain carbocycles, and heterocyclic systems. Other classes of donor-acceptor-substituted cyclopropanes are also regarded emphasizing new developments. Although preparative aspects are strongly accentuated, interesting mechanistic features, characteristic for this type of three-membered rings, will also be discussed.

Functionalised cyclopropenes as synthetic intermediates,e potential and actual uses of cyclopropenes. This may perhaps be a reflection of the perceived difficulty in handling such species, but probably also results from the rather limited routes to cyclopropenes, and in particular those bearing other functional groups, compared to the variety available w

Jacques R. Y. Salaünted, the production of new PhDs has not fallen apace, producing yearning masses of adjunct working poor (see Stanton et al., 2007). At the same time, the cultural prestige of the humanities is undergoing “momentous decline” (Hunt 1997, 17). In literary study, things may be worst of all.
