Abstract: A green approach was developed for synthesizing a series of (isatin‐3‐ylidene)‐hydrazonamides 3a–j from the reaction between isatin, (isatin‐3‐ylidene)malononitrile, or 2‐cyano‐2‐(2‐isatin‐3‐ylidene)acetate and benzohydrazonamide in ethyl acetate solutions at ambient temperature. The structures of the new compounds… read more here.

DOI: 10.1021/acsami.1c17308
Abstract: In this report, we synthesized two series of deep-blue-emitting homoleptic iridium(III) phosphors bearing 1,2,4-triazol-3-ylidene and 5-(trifluoromethyl)-1,2,4-triazol-3-ylidene cyclometalate. Compared with reported synthetic routes using Ag2O as the promoter, herein, we adopted a different strategy to furnish… read more here.
