N2 - Different 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.
