Yield:554-14-3 87 %Chromat.
Reaction Conditions:
with ethanol;cobalt(II) tetrabutylporphyrin;potassium hydroxide at 150; for 1 h;Inert atmosphere;
Steps:
2-Bromo-5-methylthiophene.
2-Bromo-5-methylthiophene (1t)(8 m L, 0.07 mmol), Co(tbp) (2.2 mg, 0.0037 mmol) and KOH(154.7 mg, 2.8 mmol) were added in EtOH (1.0 mL). The mixturewas degassed for three freeze-pump-thaw cycles, purged with N2,and heated to 150C for 1 h. 87% of 2-methylthiophene wasdetected by GC-MS analysis using decalin as internal standard.
