wherein
X represents I, Br, Cl, alkylsulfonate, or arylsulfonate;
Z represents optionally substituted aryl, heteroaryl or alkenyl;
L represents hydrogen or a negative charge;
catalyst comprises a copper atom or ion, and a ligand;
base represents a Bronsted base;
R represents H, optionally substituted alkyl, cycloalkyl, aralkyl, aryl, or heteroaryl;
R' represents independently for each occurrence H, alkyl, cycloalkyl, aralkyl, aryl, or heteroaryl, formyl, acyl, -CO2R", -C(O)N(R)2, sulfonyl, -P(O)(OR")2, -CN, or -NO2;
R" represents independently for each occurrence optionally substituted alkyl, cycloalkyl, aralkyl, aryl, or heteroaryl; and
C (R')2(R) taken together may represent nitrile.
