Abstract
AbstractDifferent cyclic (alkyl)(amino)carbenes (CAACs) were reacted with yellow arsenic. Several products [(CAAC‐n)2(μ,η1:1‐As2)] (n=1 (1), 4 (2)), [(CAAC‐2)3(μ3,η1:1:1‐As4)] (3) and [(CAAC‐3)4(μ4,η1:1:1:1‐ As8)] (6) were isolated due to the differing steric properties of CAAC‐1‐4. The products contain As2, As4 or As8 units and represent the first examples of CAACs‐substituted products of yellow arsenic. The reactivity of As4 was compared with the reactivities of P4 and the interpnictogen compound AsP3, which led to a series of phosphorus‐containing derivatives such as ([(CAAC‐3)3(μ3,η1:1:1‐P4)] (4) and [(CAAC‐3)4(μ4,η1:1:1:1‐P8)] (7)) and [(CAAC‐3)3(μ3,η1:1:1‐AsP3)] (5). The products were characterized by spectroscopic and crystallographic methods and DFT computations were performed to clarify their formation pathway.
