endo-7-Chloro-7-phenyl-2-oxabicyclo[4.1.0]heptane

Abstract

Abstract. C12H13OC1, F.W. 208-7; monoclinic, P21/c; a= 11.929 (1), b=7.469 (1), c= 11.900 (2) A, fl=96.25 (1) °; Dx= 1.315 g cm-3 for Z=4, Do= 1.317 g cm-3; V= 1054 A3;/t=28.9 cm -1. The structure was solved by the heavy-atom method and refined to R=0.074.The tetrahydropyran ring is in an envelope conformation with only one atom being significantly out of the plane defined by the other five non-hydrogen atoms of that moiety. The phenyl ring is oriented parallel to the bridgehead bond of the bicyclic system. endo-7-CHLORO-7-PHENYL-2-OXABICYCLO[4,1,0]HEPTANE
