Paragraph 0006; 0014-0017, (2021/07/14)
The invention discloses a method for synthesizing a tert-butyl diphenylphosphine compound, and belongs to the field of organic synthesis. The method comprises the following step: in an anhydrous and oxygen-free atmosphere, tert-butyl alcohol is taken as a raw material and reacts with diphenylphosphine under the action of a catalyst to generate tert-butyl diphenylphosphine. Compared with the prior art, the method has the advantages of mild reaction conditions, simple operation, high yield, simple and easily available raw materials and reduced production cost, and is suitable for industrial production.

Asymmetrically substituted tertiary phosphines and quaternary phosphonium salts are used extensively in applications throughout industry and academia. Despite their significance, classical methods to synthesize such compounds often demand either harsh reaction conditions, prefunctionalization of starting materials, highly sensitive organometallic reagents, or expensive transition-metal catalysts. Mild, practical methods thus remain elusive, despite being of great current interest. Herein, we describe a visible-light-driven method to form these products from secondary and primary phosphines. Using an inexpensive organic photocatalyst and blue-light irradiation, arylphosphines can be both alkylated and arylated using commercially available organohalides. In addition, the same organocatalyst can be used to transform white phosphorus (P4) directly into symmetrical aryl phosphines and phosphonium salts in a single reaction step, which has previously only been possible using precious metal catalysis.

Synthetic and structural aspects of the phosphanylation of 1,3benzazaphospholides 1L1, ambident benzofused azaphosphacyclopentadienides, are presented. The unusual properties of phospholyl-l,3,2-diazaphospholes inspired us to study the coupling
