摘要:

Natural abundance17O NMR chemical shift data for 12 variably hindered aryl acid chlorides recorded in acetonitrile at 75° C are reported. The17O NMR signals for the hindered acid chlorides are deshielded relative to unhindered isomers. A quantitative relationship between molecular mechanics (MM2) estimated torsion angles and17O NMR chemical shifts for the aryl acid chlorides is developed.
