## Abstract Chemical shifts are reported for the acetyl protons in a series of __para__βsubstituted acetophenones in a number of solvents, and substituent effects evaluated statistically by means of the SwainβLupton multiple correlation analysis. A basic set of substituents was built up by careful
## New systems of the type M(pyrenNRz)Br, M(pyrtn NRJBr (M = Cu, Ni), M(pyr)(pyrenNR,) (M = CM, Ni), Cu(pyr)(pyrtnNR,) (where Hpyr is pyrrole-2aldehyde, pyrenNR, is Schiff base of pyr and NR,CH, CH2NH, andpyrtnNR, is Schiff base ofpyr and NR2CH2 CH2CH2NH2) are reported. The first two systems are sho
