Abstract

The ^13^C and ^1^H NMR spectra of 1‐OH‐, 2‐OH‐, 1,2‐diOH‐, 1‐OAc‐, 2‐OAc‐ and 1,2‐diOAc‐9,10‐anthraquinone were assigned. The hypothesis that substituent‐effect additivity could be used as a chemical shift assignment tool was tested, with satisfactory results. For all compounds, errors were found in previous assignments. The NOE technique combined with SEFT, heteronuclear decoupling and 2D heteronuclear one‐bond correlation experiments were used for the assignment of the different resonances.

A series of 3-substituted(X)bicyclo [ 1.1.1 ] pent-1-yltrimethylstannanes (3) were synthesized and their 119Sn and 13C NMR spectra were recorded. The 119Sn substituent chemical shifts (SCS) and the one-bond carbon-tin coupling constants [ 1J(13C,119Sn) ] were analyzed in terms of possible substituen
