| | 4-NITROPHENYLACETYLENE Usage And Synthesis |
| Chemical Properties | Light Yellow Solid | | Uses | 4-Nitrophenylacetylene (cas# 937-31-5) is a compound useful in organic synthesis. | | Synthesis Reference(s) | Tetrahedron, 62, p. 6673, 2006 DOI: 10.1016/j.tet.2005.12.077 | | Synthesis | 4-Nitrophenylacetylene is synthesized in two steps. Step 1: 1-Iodo-4-nitrobenzene and (trimethylsilyl)acetylene react in DMF at 50C in the presence of Pd(PPh3)2Cl2, CuI, and Et3N to yield [4-(nitrophenyl)ethynyl]trimethylsilane. Step 2: This silyl derivative is treated with TBAF in THF at 0C. After quenching, extraction and purification give 4-nitrophenylacetylene. |
