Dave-Phos

Scheme 15a) (2008JA3276, 2009JA3291). Selective C2-arylation ofthia-zole N-oxide 33 can be obtained under mild conditions (Pd(OAc)2, Dave-Phos, K2CO3, PivOH in toluene at room temperature) (33 34) (F pre... 

Sulfonates derived from nucleosides were coupled with aryl amines by Laksh-man [197], who used Pd(OAc)2 and Dave-Phos as the catalytic system, along with K3PO4 as base, giving rise to a wide range of aryl amines in 1,4-dioxane/t-BuOH as solvent mixture. 

Continuing on the topic of aryl chloride substrates, in 2011, Xu etal. [45] reported the use of mUd reaction conditions using tetrabutylammounium acetate (TBAA) as base, a range of olefin products could be obtained in very high yields. The conditions are shown in Figure 1.4, along with some prominent examples. Dave-Phos was used as the ligand.
