Considerable effort is being expended toward the understanding of the nature of strained carbon-carbon single bonds.2 In this respect, strained propellanes are very 1nstructive.e We wish to report syntheses for and reactivities of two new C4.2.11 propellanes; we feel the results contribute

## Abstract The ^13^C NMR spectra of tricyclo[4.2.1.0^2,5^]nonanes and tetracyclo[5.4.1.0^2,6^.0^8,11^]dodecanes and their dimethyl derivatives were measured to demonstrate the four‐membered ring annelation effects on the bicyclo[2.2.1]heptane skeleton, and the steric δ‐__syn__ effects of the methy
