摘要

5-Chlorodibenzophosphole and 10-chlorophenoxaphosphine have been prepared in 6 and 24% yields, respectively, by dehydrohalogenation of 2-biphenylyl-and 2- phenoxyphenylphosphonous dichlorides. The phosphonous dichlorides were not isolated but underwent cyclization during the manipulations incident to their attempted isolation. 2- Benzylphenylphosphonous dichloride, however, could be isolated. It underwent ...
