Application of 444-29-1,Some common heterocyclic compound, 444-29-1, name is 1-Iodo-2-(trifluoromethyl)benzene, molecular formula is C7H4F3I, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: In a typical experiment, the isolated crystalline precatalyst 1A (or 2A, 0.005 mmol) was sequentially mixed with 3 mL of solvent (DMF or [Bmim]PF6 if required), iodobenzene (5mmol), phenylacetylene (6 mmol), and Et3N (7.5 mmol). The obtained mixture was placed in a sealed Teflon?lined stainless steel autoclave, purged with syngas (CO, 1.0 MPa) and then stirred vigorously at the required temperature for the appointed time. Upon completion of the reaction, the mixture wasc ooled to room temperature and the pressure was carefully released. The reaction mixture was extracted with diethyl ether(5 mL 3). The ether fractions were combined and then analyzedby GC to determine the conversion of PhI (1?dodecane as an internal standard) and the selectivity for the carbonylative products (normalization method). The structures of the carbonylative products were further confirmed by GC?MS.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1-Iodo-2-(trifluoromethyl)benzene, its application will become more common.
