Bulky N-Substituted 1, 3-Benzazaphospholes: Access via Pd-Catalyzed C− N and C− P Cross Coupling, Lithiation, and Conversion to Novel P C− P t Bu2 Hybrid …
We recently reported a convenient access to 1H-1,3-benzazaphospholes by reductive cyclization of 2-phosphonoanilides, but N-substituted derivatives have so far been obtained only by multistep procedures starting with dilithiation of N-methyl-2-bromoaniline.(14) N-Alkylation, a convenient
