      Direct ToF-SIMS analysis of organic halides and amines on TLC plates
      A. PARENT, T. ANDERSON, D. MICHAELIS, G. JIANG, P. SAVAGE, M. LINDFORD* (*Department of Chemistry and Biochemistry, Brigham Young University, Provo, UT 84602, United States, mrlindford@chem.byu.edu)

      Appl. Surf. Sci. 252, 6746-6749 (2006). To show the application of direct time-of-flight secondary ion mass spectrometry (ToF-SIMS) to analyze a reaction mixture between an alpha-bromoamide (1), and picolylamine, to form the substitution product (3) via SN2 (1 and 3 are indistinguishable by TLC on silica gel with dichloromethane – methanol – ammonia 100:15:2), a series of organic halides with widely differing structures (trifluoromethanesulfonamide, a vinyl bromide, a silyl-protected primary bromide, and iodosobenzene diacetate) were separated on TLC plates under the same conditions. The resulting spots and background were analyzed by positive and negative ion spectra. In all cases, the halide signals were notably stronger than the background signals. In addition, a series of amines (1,1-carbonyl diimidazole, norepinephrine, adenosine, and cinchonidine) was separated on TLC plates and analyzed directly by ToF-SIMS. In all but one (adenosine), even quasi-molecular ions were observed.

TLC of uroporphyrin I, uroporphyrin III, coproporphyrin I, coproporphyrin III, and protoporphyrin IX (as methyl esters) on polyamide 11, cellulose and silica gel with methanol, ethanol, propanol, butanol, acetonitrile and tetrahydrofuran in a saturated chamber. Porphyrins on cellulose were detected by placing in iodine vapor for 5 min; on silica gel and polyamide 11 the porphyrins were detected as red spots in UV light at 254 nm. Chromatographic retention data and a possible retention mechanism are discussed.
