在碳酸钾和18-冠-6存在下，二羟基（四芳基卟啉）磷（V）配合物与几种溴代烷在乙腈中进行O-烷基化反应，得到了中等产率的二烷氧基（四芳基卟啉）磷（V）配合物。将类似的O-烷基化应用于二羟基（四芳基卟啉）锑（V）配合物。的O-烷基化进行的发生的SN 2攻击的烷氧基阴离子的络合物在碳取代的卤化物。
The O-alkylation of dihydroxo(tetraarylporphyrinato)phosphorus(V) complexes with several kinds of alkyl bromide in MeCN in the presence of K2CO3 and 18-crown-6 ether produced dialkoxo(tetraarylporphyrinato)phosphorus(V) complexes in-moderate-good yields. Similar O-alkylation was applied to dihydroxo(tetraarylporphyrinato)antimony(V) complexes. The O-alkylation proceeded by the occurrence of an SN2 attack of the alkoxide anion of the complexes at the carbon substituted with halides.
