Preparation and structure investigations of simple bicyclo[1.1.0]butanones
Rauk,Sorensen,Sun
, p. 4506 - 4514 (2007/10/02)
Four 1,3-dialkyl-substituted bicyclo[1.1.0]butanones have been prepared. All have been completely characterized by 1H and 13C NMR spectroscopy, but 17O NMR proved to be particularly diagnostic. The di-t-Bu 4 and di-tert-am
