The Ni-catalyzed carboacylation of alkynes with amide electrophiles and triarylboroxines is presented. The reaction generates all-carbon tetrasubstituted alkene products in up to 62% yield. NiCl2·glyme is used as an inexpensive precatalyst in the absence

The reaction of racemic diarylmethylamines, (Ar1Ar2CHNR2), where Ar1 is substituted with a 2-hydroxy group, with arylboroxines (Ar3BO)3 in the presence of a chiral diene-rhodium catalyst gave high yields of chiral triarylmethanes (Ar1Ar2CH?Ar3) with high enantioselectivity (up to 97% ee). The reaction is assumed to proceed through o-quinone methide intermediates which undergo Rh-catalyzed asymmetric 1,4-addition of the arylboron reagents.
Rhodium-catalyzed asymmetric hydroarylation of 3-pyrrolines giving 3-arylpyrrolidines: Protonation as a key step
So, Chau Ming,Kume, Satoshi,Hayashi, Tamio
supporting information, p. 10990 - 10993 (2013/08/23)
A hydroxorhodium complex coordinated with (R)-segphos was found to catalyze the hydroarylation of 3-pyrrolines with arylboroxines under neutral conditions to give 3-arylpyrrolidines with high enantioselectivity in high yields.
