摘要：

Polarisation of (19)F-nuclei during the insertion of triplet diphenylmethylene into the benzylic C-H bond of individual, optically active, diastereoisomeric 1-methyl-heptyl alpha-fluorophenylacetates appears equally in both diastereoisomeric products, indicating that the radical pairs giving rise to CIDNP show no stcreochemical preference in their combination.
