摘要：

Heating of bis[bis(diisopropylamino)phosphanyl]diazomethane 7, in refluxing benzene for 48 hours, quantitatively led to the corresponding 1, 2A1-azaphosphetane 9 as only one diastereoisomer. This result is explained in terms of carbene insertion into a methin-CH bond of an isopropyl substituent. The regiospecificity and the stereospecificity of the ring closure is discussed. Treatment of 9 with elemental sulfur afforded the corresponding 1, 2, 2A -azathiophosphetane 10 which has been characterized by X-ray crystallography: C2sHshN.
