Abstract
Oxa(l.1.l)propellane (2), dioxa(l.1.l)propellane (3), and trio-·
xa(l.l.l)propellane (4) have been studied by means of ab initio
SCF MO technique at 6-31G* level. The geometry optimization
is carried out for these molecules and the parent hydrocarbon
(1.1.l)propellane. The bond between the two bridgehead carbon
atoms is predicted to be in (2) : 1.503 A, (3) : 1.474 A, and (4) : 1.456
A. These are shorter than the calculated central bond (1.543 A)
in (1.1.l)propellane.
