The phosphonium salt 2, generated by adding 2,4,4,6-tetrabromo-2,5-cyclohexadienone1 to triphenylphosphine in CH3CN-THF or 1,2-dichloroethane converted sterically less congested silyl ethers directly to the corresponding bromides in high yields.
通过在CH 3 CN-THF或1,2-二氯乙烷中的三苯基膦中添加2,4,4,6-四溴-2,5-环己二酮1生成的phospho盐2,将空间上较少拥挤的甲硅烷基醚直接转化为相应的溴化物。高产。
