## Abstract ^11^CβMethyl labelled 1,1β²βdimethylβ4,4β²βdipyridinium diiodide has been prepared by reaction of ^11^Cβiodomethane with 4,4β²βdipyridyl dihydrate. Radiochemical analysis of the product was by electrophoresis. The ^11^Cβiodomethane precursor was prepared rapidly from cyclotron produced ^11
The mass spectra of a number of the epimeric 1,2-dimethyl-4-alkyl-4-hydroxydecahydroquinolines (alkyl: C z C H , CH=CH,, C,H, and COCH,) have been studied. The configuration at C-2 and C-4 in these molecules is proposed on the basis of the data obtained. Some aspects of the fragmentation pathways un
