The bonding in the As 6 4À ion is studied in the unusually low-coordination environment provided by the compound {Rb[18]crown-6)} 2 Rb 2 As 6 •6 NH 3 . Theoretical analysis of the related P 6 4À ion indicates an unusual P¼P bond which contains major contributions from the lone pairs. Outside a highl
## Abstract The nature of the bonding between bridgehead carbon atoms (Ca, Ca′) as well as the ring strain in a family of 10 propellanes formed by three‐, four‐, or five‐member rings: [1.1.1] (I), [2.1.1] (II), [3.1.1] (III), [2.2.1] (IV), [3.2.1] (V), [2.2.2] (VI), [3.3.1] (VII), [3.2.2] (VIII), [
## Abstract The thermal cyclization of the phosphane oxide substituted enyne‐allene 1d results in the formation of 4d, an unknown double‐bond shift isomer of the 11__H__‐benzo[__b__]fluorene system. Because of the completely hindered rotation about the PC bond, two rotamers could be isolated and i
