Abstract
Four new fluorinated aldehydes (5-Rf S-2-furfuraldehyde; Rf = 4-CF3 C6 F4 for 1 , 4-C6 HF4 for 2 , 4-CF3 C6 H4 for 3 and 2,4-C6 H3 F2 for 4 ) derived from 5-bromo-2-furfuraldehyde have been prepared. Treatment of compounds 1 -4 with thiosemicarbazide afford the corresponding 5-Rf S-2-furfuraldehyde thiosemicarbazones (Rf = 4-CF3 C6 F4 for 5 , 4-C6 HF4 for 6 , 4-CF3 C6 H4 for 7 and 2,4-C6 H3 F2 for 8 ). The molecular structure of compound 6 has been determined.
Key words
fluorine - furans - sulfur - thiosemicarbazones - furfuraldehyde
