Chen, Jianyang published the artcileFacile one-pot synthesis of diarylacetylenes from arylaldehydes via an addition-double elimination process, Safety of 3-Chlorobenzylchloride, the publication is Organic & Biomolecular Chemistry (2021), 19(21), 4701-4705, database is CAplus and MEDLINE.
A practical one-pot protocol has been developed to synthesize diarylacetylenes ArCCAr1 (Ar = Ph, naphthalen-1-yl, furan-2-yl, etc.; Ar1 = Ph, 4-chlorophenyl, naphthalen-2-yl, etc.) from arylaldehydes ArCHO by treatment with 1-(arylmethyl)benzotriazoles I and LiN(SiMe3)2. The reaction proceeded through imine formation, Mannich-type addition and double elimination to deliver products in up to 99% yields with broad substrate scope. In addition, gram-scale synthesis of diarylacetylene (Ar = 4-bromophenyl, Ar1 = Ph) has been demonstrated.
Organic & Biomolecular Chemistry published new progress about 620-20-2. 620-20-2 belongs to chlorides-buliding-blocks, auxiliary class Chloride,Benzyl chloride,Benzene, name is 3-Chlorobenzylchloride, and the molecular formula is C7H6Cl2, Safety of 3-Chlorobenzylchloride.
