Triphenylphosphine: onye so na phosphines nke atọ
Triphenylphosphine (TPP) bụ otu n'ime phosphines nke atọ, nke bụ phosphane, ebe otu phenyl na-anọchi hydrogen atọ ahụ. Ọ nwere ọrụ dị ka ihe na-ebelata ihe na ihe nnọchi anya mgbanwe kemịkalụ NMR. Ọ bụ ligand dị mkpa ejiri na mmeghachi omume Wittig maka mmepụta alkene. Mmeghachi omume a gụnyere ịmepụta alkyliden-etriphenylphosphoranes site na ọrụ nke butyllithium ma ọ bụ ntọala ọzọ na quarternary halide. A na-eji Triphenylphosphine emepụta ihe ndị dị ndụ n'ihi na ọ bụ nucleophilic na njirimara ya na-ebelata.
