A. Maestro et al., SYNTHESIS OF (ISOXAZOL-4-YLMETHYL)TRIPHENYLPHOSPHONIUM SALTS DERIVED FROM 5-ALKYL-3-METHYLISOXAZOLES AND 5-ARYL-3-METHYLISOXAZOLES, Synthesis, (8), 1998, pp. 1104-1106
The synthesis of (isoxazol-4-ylmethyl) triphenylphosphonium salts deri
ved from 5-alkyl- and 5-aryl-3-methylisoxazoles has been carried out.
This method involves the preparation of several 4-(chloromethyl)isoxaz
oles which are suitable precusors for these phosphonium salts. The pho
sphonium salts were completely characterized by spectroscopic methods
and were obtained in very good to quantitative yields.
