-
Paragraph 0057-0060, (2020/08/27)
The invention relates to an aryl dithioformate compound with a large steric hindrance group and application of the aryl dithioformate compound as an RAFT reagent. The RAFT reagent is simple in synthesis process and easy to separate and purify, the product can be stored for a long time, RAFT polymerization of high-activity monomers and low-activity monomers can be controlled, and block polymers ofthe high-activity monomers and the low-activity monomers can be synthesized through the RAFT reagent.

By using mechanistic insight, a new ligand (EPhos) for the palladium-catalyzed C?N cross-coupling between primary amines and aryl halides has been developed. Employing an isopropoxy group at the C3-position favors the C-bound isomer of the ligand-supported palladium(II) complexes and leads to significantly improved reactivity. The use of a catalyst system based on EPhos with NaOPh as a mild homogeneous base proved to be very effective in the formation of 4-arylaminothiazoles and highly functionalized 2-arylaminooxazoles. Previously, these were not readily accessible using palladium catalysis.

Tris(2,6-diisopropyl-4-methoxyphenyl)phosphine (1) was synthesized to investigate substituent effect of methoxy groups on the properties of crowded triarylphosphines. Methoxy groups slightly lower the first oxidation potential of 1 and contribute blue-shi
