Paragraph 0305-0308; 0310-0313; 0315, (2020/01/25)
The invention relates to an alpha-aryl or alkyl substituted borane adduct, a preparation method and applications thereof, specifically to preparation of an alpha-aryl or alkyl substituted borane adduct by carrying out a reaction on hydrazone as an unstabl

A highly enantioselective synthesis of trisubstituted allenes has been achieved through Cu(I)-catalyzed cross-coupling of aryldiazoalkanes and terminal alkynes with chiral bisoxazoline ligands. Alkynyl migratory insertion of Cu(I) carbene is proposed as t

A novel, catalytic enantioselective route to synthesize a variety of α-tertiary aryl ketones via a boron Lewis acid promoted formal insertion of aryldiazoalkane into the C-H bond of both aromatic and aliphatic aldehydes is described. In the presence of ch
A significant barrier to 1,2 hydrogen migration in singlet 1-phenylethylidene. A laser flash photolysis study
Sugiyama, Michelle H.,Celebi, Sol,Platz, Matthew S.
, p. 966 - 973 (2007/10/02)
Laser flash photolysis of 1-phenyldiazoethane in heptane releases 1-phenylethylidene which can be intercepted with pyridine to form an ylide (λmax> = 475 nm). Oxygen trapping experiments indicate that relaxation of singlet 1-phenylethylidene to
