Twice, and faster : Reaction of the zwitterionic silylene 1 with AsH 3 occurs stepwise at ambient temperature to give the first crystalline, donor‐stabilized arsasilene 3 via its 1,1‐addition product (silylarsane 2 ). In contrast, the activation of PH 3 by 1 merely leads to the phosphorus analogue of 2 . The strikingly different metal‐free activation of the series of Group 15 hydrides EH 3 (E=N, P, As) by 1 was rationalized with DFT calculations.
