Unprecedented formation of isoxazole in the reaction between nitromethane and BF3·Et2O in the presence of ethylene
摘要:
The reaction in air between nitromethane and BF3. OEt2 in the presence of ethylene gives isoxazole which has been trapped by platinum(II) through reaction with (Ph-3-PCH2Ph)(2)[PtCl4] to produce the isoxazole complex (Ph-3-PCH2Ph)[PtCl3(C3H3NO)] which has been characterized spectroscopically, crystallographically and by independent synthesis.
