alkyl group or a group polymerizable photochemically and/or thermally via an organic group by radical or cationic polymerization, provided the group does not contain aryl. The silane resins have dielectric properties useful in extremely high frequency applications.
Crystal structures of three novel dioxotetraperoxodi(molybdenum) heteropolyanions in [PPh4]2[R2SiO2{Mo2O2(μ-O2)2(O2)2}] (R2=(CH3)2, (i-C4H9)2 or (CH3)(CH2Cl)) and characterization of their tungsten analogues
[PPh4]2[R2SiO2M2O2(μ-O2)2(O2)2}] in 75–80% isolated yields (R2 = (CH3)2, (i-C4H9)2 or (CH3)(CH2Cl); R′=CH3R′=CH3 or C2H5; M = Mo(VI) or W(VI)). These results are unequivocally established by a combination of elemental analysis, IR, 1H and 13C NMR spectroscopy and complete X-raycrystalstructure analysis of the three molybdenum complexes.There is good evidence that the tungsten analogues are isostructural compounds
MoO 3 [或“ WO 3 ·H 2 O”],H 2 O 2(30 wt%)水溶液与R 2 Si(OR ')2 R2Si(OR')2在碱性过氧化氢-乙醇混合物中的反应通过用PPH治疗4 +氯-得到先前未知的dioxotetraperoxodi(钼或钨)杂,的相应的盐[PPH 4 ] 2 [R 2的SiO 2 M 2 ö 2(μ-O 2)2(O 2)2 }]的分离产率为75–80%(R 2 =(CH 3)2,(i -C 4 H 9)2或(CH 3)(CH 2 Cl); R ' = CH 3 R'= CH3或C 2 H 5; M = Mo(VI)或W(VI))。结合元素分析,IR,1 H和13明确确定了这些结果C NMR光谱和三个钼complexes.There的完整X射线晶体结构分析是良好的证据表明,钨类似物是同构compounds.The O-O键是在1.464-1.483的范围内,典型的过氧配合物η
