13C-labeled dicarboxylic acids HO213C-(CH2)n-13CO2H (n = 10, 12, 14, 16, 18, 20, 22, 24, 26, 28) have been synthesized as internal standards for LC-MS and GC-MS analysis of cutin and suberin monomer degradation by soil-based microorganisms. Different synthetic strategies had to be applied depending on the chain length of the respective synthetic target and because of economic considerations. 13C-labels were introduced by nucleophilic substitution of a suitable leaving group with labelled potassium cyanide and subsequent hydrolysis of the nitriles to produce the corresponding dicarboxylic acids. All new compounds are characterized by GC/MS, IR, and NMR methods as well as by elemental analysis.

Alkenyl tosylates of the type RCH=CH(CH2)nOTs undergo metathesis using a WCl6-Me3SnCl catalyst system, producing difunctionalised alkenes of the type TsO(CH2)nCH=CH(CH2)nOTs (n=7,8, and 9); examples of the use of
