本文改进了Jownt合成MoO[S_2P(OEt)_2]_2的方法,还发现了两个新的合成方法。合成了新加合物MoO(S_2CNEt_2)_2·(Ac)(Ac=CH≡CCH_2OH,CH≡CCH_2OEt,CH≡CCH_2C1,CH≡CCH_2Br,HOCH_2C≡CCH_2OH)和MoO[S_2P(OEt)_2]_2·(EtO_2CN=NCO_2Et)。研究了Mo_2O_3[S_2P(OEt)_2]_4·、MoO(S_2P(OEt)_2)_2、Mo_2O_3(S_2CNEt_2)_4、MoO(S_2CNEt_2)_2,Mo_2O_3(S_2COEt)_4(以下分别简写为P(5)、P(4)、N(5)、N(4),O(5))络合和活化炔类化合物的性能,并发现与炔键络合的是Mo(Ⅳ)络合物,且含硫配位体的供电子能力愈强,Mo(Ⅳ)络合物络合和活化炔键的能力亦愈强。
In this paper, the method of synthesizing MoO [S_2P (OEt) _2] _2 by Jownt was improved and two new synthetic methods were also found. The new adducts MoO (S 2 CNEt 2) 2 · (Ac) (Ac = CH≡CCH 2 OH, CH≡CCH 2 OEt, CH≡CCH 2 Cl, CH≡CCH 2 Br, HOCH 2 C≡CCH 2 OH) and MoO [S 2 P (OEt) EtO 2 CN = NCO 2 Et). The effects of Mo 2 O 3, Mo 2 O 3, Mo 2 O 4, Mo 2 O 4, Mo 2 O 4, Mo 2 O 4, Mo 2 O 4, Mo 2 O 3, (4), N (5), N (4), O (5)) complexes and activated acetylenic compounds, and found that the acetylenic bond is Mo (Ⅳ) complex and sulfur The stronger the electron donating ability of the ligand, the stronger the ability of complexing and activating acetylene bond of Mo (Ⅳ) complex.
