A Rh-catalyzed intermolecular coupling of diazomalonates with arene C-H bonds is reported. The reaction is initiated by electrophilic C-H activation, which is followed by coupling of the arylrhodium(III) complex with the diazomalonate. In most cases, arenes with oximes, carboxylic acids, and amines as directing groups cross-couple with diazomalonates with excellent regioselectivities and functional group tolerance, and thus, this reaction offers a new route to α-aryl carbonyl compounds for specific applications.

In this paper, we present a consensus algorithm for synchronous distributed systems using cooperating mobile agents. The algorithm is designed within a framework for mobile agent enabled distributed server groups (MADSG), where cooperating mobile agents are used to achieve coordination among the servers. Being autonomous and cooperative, cooperating mobile agents exchange information among themselves to achieve consensus. The correctness proof of the proposed algorithm is presented. Performance evaluation of the algorithm has been carried out by both theoretical analysis and simulation.
