Crystal structures of two new 3-(2-chloroethyl)-r(2),c(6)-diarylpiperidin-4-ones

The syntheses and crystal structures of 3-(2-chloroethyl)-r-2,c-6-diphenylpiperidin-4-one, C19H20ClNO, (I), and 3-(2-chloroethyl)-r-2,c-6-bis(4-fluorophenyl)piperidin-4-one, C19H18ClF2NO, (II), are described. The piperidone ring adopts a chair conformation in (I), whereas a slightly distorted chair...
