Various Adducts from Ketones, Diazocyanides, and Nitrosobenzene with (Methylidenamino)phosphines (Methylidenamino)phosphine 1a reacts with activated ketones to 2,7‐dioxa‐5‐aza‐1λ 5 ‐phosphabicyclo‐[3.2.0]heptanes 2a, b and with nitrosobenzene to l, 3,5,2λ 5 ‐oxadiazaphosphole 3a . The reaction of 1b with nitrosobenzene and diethyl mesoxalate yields 2,7‐dioxa‐3,5‐diaza‐1λ 5 ‐phosphabicyclo[3.2.0]heptane 4 . With the cyano group of diazocyanides, 1a reacts to the adducts 5a–d . The structure of 5a is proven by an X‐ray diffraction analysis.
