Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 141998-92-7, name is 5-Iodo-1-phenyl-1H-pyrazole, A new synthetic method of this compound is introduced below., SDS of cas: 141998-92-7<\/a><\/p>\n

A) 1-phenyl-5-[(trimethylsilyl)ethynyl]-1H-pyrazole To a solution of 5-iodo-1-phenyl-1H-pyrazole (2.00 g) (J. Org. Chem. 2008, 73, 1, 177-183) in triethylamine (40.0 mL) were added ethynyl(trimethyl)silane (0.80 g), CuT (0.141 g) and PdCl2(PPh3)2 (0.260 g) under an argon atmosphere, and the mixture was stirred at 70 C. for 10 hr. The reaction mixture was filtered, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (dichloromethane) to give the title compound (1.54 g). 1H-NMR (400 MHz, CDCl3) delta 0.00 (9H, s), 6.42 (1H, d, J=1.6 Hz), 7.12-7.16 (1H, m), 7.23 (1H, t, J=16 Hz), 7.42 (1H, d, J=1.6 Hz), 7.58-7.60 (2H, m)<\/p>\n
