Triphenyl radical
WebTriphenyltin hydride can be used as a reducing agent in: The reductive deselenenylation reaction in the presence of the catalytic amount of AIBN. The free radical hydrostannylations of olefins. The reduction of α, β-unsaturated ketones and esters. WebThe most common forms of triphenyl methyl used are malachite green and basic violet. Malachite green has been commonly used as ectoparasiticide and fungicide in fish farming since 1936. In Africa, it has been employed against the infection of protozoans, nematodes, bacteria, cestodes, crustaceans, etc. ( Srivastava, Sinha, & Roy, 2004 ).
