Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 5931-53-3, C19H17P. A document type is Patent, introducing its new discovery., Safety of Diphenyl(o-tolyl)phosphine
The invention belongs to the technical fields of medicine and natural compound chemical intermediates and related chemical technology, provides a preparation method, uses diphenylphosphine compound and aryl halide as raw materials, does not need transition metal catalysis and participation, under heating conditions, a triaryl phosphine compound is further constructed in one step. The method has the beneficial effects that no metal or non-metal catalyst is used for catalytic reaction, no pollution, mild reaction conditions, simple operation and post-treatment, and good substrate compatibility are achieved.
