P,P,P′,P′-Tetraethynylated Bisphosphine and P-C-P Pincer Ligands with Bulky End Caps: Synthesis, Coordination Properties and Application to Platinum-catalyzed 1,8-Enyne Cycloisomerization
P,P,P′,P′-Tetraethynylated bisphosphine and P-C-P pincer ligands with tris[3,5-di(tert-butyl)-4-methoxyphenyl]methyl end caps were synthesized. The bulky end cap groups of these ligands form a nano...
