1. C1 Building Blocks: New Approaches for Thiomethylations and Esterification
Abstract : The thioether motif is found in numerous pharmaceuticals. The simplest form of this motif, the methyl-thioether is similarly found in many biologically active compounds and has exhibited many advantageous properties. The installation of the thiomethyl moiety can be troublesome due to the toxicity and malodor of small sulfur reagents. READ MORE

2. Bis(4-chlorophenyl) sulfone and PCB methyl sulfone metabolites : Trends and chirality in the Baltic Sea environment
Abstract : The Baltic Sea was earlier identified as a highly polluted brackish water body and still is. The high concentrations of polychlorinated biphenyls (PCBs), p,p’-DDT and related compounds led to severe effects on several species in the Baltic region. READ MORE

4. Effects of methyl jasmonate on chemical defenses of conifer seedlings in relation to feeding by Hylobius abietis
Abstract : The chemical elicitor methyl jasmonate (MeJA) could replace insecticides in Europe and Asia for protection of young conifers against the pine weevil (Hylobius abietis). This thesis mainly focuses on the effects of MeJA treatment on chemical defenses of conifers from seedling batches with documented field resistance. READ MORE

5. Stable bromine isotopic composition of methyl bromide : Method development and applications
Abstract : The isotopic composition of ozone depleting methyl halides may provide valuable information on the sources and sinks of these compounds. However, so far mostly stable carbon isotope analysis of methyl chloride and methyl bromide (CH3Br) has been attempted. READ MORE
