Abstract
Five‐ and Six‐Membered Cyclic Phosphonic Diamides, Thioester‐amides and Spirobi[oxazaphospholes]
By reaction of the 1,2‐diaminobenzene derivatives 1a–d with the phosphonoyl dichlorides 2a–g, the 1,3‐dihydro‐1,3,2‐benzodiazaphosphol‐2‐ones 4a–q are obtained. The phosponoyl dichlorides 2a–e, 2g, and 2h yield with naphthalene‐1,8‐diamines (5) the diazaphosphinones 6a–g under similar reaction conditions. The thiazaphosphole oxides 9a–d are accessible by reaction of the phosphonoyl dichlorides 2a–d with 2‐aminobenzenethiol (7). Unexpectedly, the reaction of the dichlorides 2a and 2b with 2‐aminophenol (10) led to the spirobi[oxazaphospholes] 13a and 13b, respectively.
