| Abstract: | Reaction of
pentachlorophosphorane with o-Aminophenol
in 1:2 mole ratio under controlled temperature conditions yields a
spirobicyclic phosphorane (1) in
which a five-membered ring with oxygen and nitrogen bonded to a pentavalent phosphorus.
However, at higher temperatures of the reaction, a benzoxazaphosphole (2)
is isolated which crystallises in a
triclinic system,
space group P‾1 and has structural
parameters of a =
8.2932 (8) Å, b =
9.4138(9 ) Å, c =10.4382(10) Å and =96.073(2)°,
β= 108.303(1)°, =112.785(1)°.
R1 = 0.0610, wR2 = 0.1178 for 1574 reflections [1> 2 σ (I)]. |
