The reaction tube was placed in a 12 tube Radley reaction carousel and the mixture was heated to 130°C and stirred for several hours. Small aliquots of reaction mixture were taken for GC analysis. The conversions and yields were determined with GLC. GLC analyses were performed using a Zebron ZB-35 column on a Perkin Elmer Autosystem. Conversions and yields were determined by using 1,3,5-tri-tert-butylbenzene as internal standard. GC/MS measurements were obtained with a Shimadzu GC/MS-QP5000 using a Zebron ZB-35 column. MALDI-TOF spectra were obtained on a PerSeptive Biosystems Voyager DE PRO spectrometer using α-cyano-4-hydroxycinnamic acid as a matrix. The products were characterized (GLC) by comparison with authentic samples (Table 2). Recycling of the catalyst was established by evaporating the reaction mixture followed by addition of fresh alcohol.
