TLDR
The reaction of 1,1-dibromo-2,2-bis(chloromethyl)cyclopropane (2) with methyllithium in ether led to a solution of [1.1]-propellane (1) in a yield of 70%.Abstract:
The reaction of 1,1-dibromo-2,2-bis(chloromethyl)cyclopropane (2) with methyllithium in ether led to a solution of [1.1.1]-propellane (1) in a yield of 70%. 1 could also be prepared free of solvent by reaction of 2 with lithium powder in triglyme/n-decane at 73°C.read more

Average local ionization energies computed on the surfaces of some strained molecules
TL;DR: In this paper, an ab initio self-consistent field molecular orbital (SCF-MO) procedure has been used to compute the average local ionization energies [I( r )] of some strained molecules on three-dimensional surfaces defined by the contour of electronic density equal to 0.002 electrons/bohr3.

TL;DR: In this paper, the interpretation of ABC-type spectra is discussed in relation to several series of calculated spectra; some frequency and intensity sum rules are indicated; these effects are probably transmitted through the sigma bonds.
