Summary
-
1.
Mixed anhydrides of ethylphosphonousacid and dialkyl hydrogen phosphites were prepared.
-
2.
It was shown that treatment of the mixed anhydrides with alkyl halides resulted in rearrangement with formation of quaternary phosphonium salts.
-
3.
Diethyl ethylphosphonodithioite was prepared.
-
4.
Diethyl ethylphosphonotrithioate was obtained by addition of sulfur to diethyl ethylphosphonodithioite.
-
5.
It was found that treatment of diethyl ethylphosphonodithioite with benzyl bromide results in the formation of dibenzylethylpbosphine sulfide and ethyl benzylethylphosphinodithioate.
