Synthetic Route of 1608-26-0, An article , which mentions 1608-26-0, molecular formula is P[N(CH3)2]3. The compound – Tris(dimethylamino)phosphine
played an important role in people’s production and life.
Tris(dimethylamino)phosphine 1 reacted with phenylarylidene barbituric acids 4 to yield the triaminophosphonium dipolar ion adduct 7. 2-Arylidene-1,3-cyclohexanedione 5 and 2-Arylidene-5,5-dimethylcyclohaxane-1,3-diones 6 reacted with phosphine 1 to produce the dioxyxanthenes 10 and 12, respectively. Structural assignments are based on analytical, chemical, and spectroscopic evidences. A mechanism is proposed to explain the formation of these compounds. The biological acitivity of the new synthesized compounds against Aphis Craccivora, a serious pest infecting many crops in Egypt, was studied.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1608-26-0, help many people in the next few years., Synthetic Route of 1608-26-0
