Reaction of Na2S·9H2O with 1,1,2,2-tetra(2,4,6-tri-isopropylphenyl)-1,2-dibromoditin in air yields the stericallyhinderedfour-membered 1-oxa-3-thia-2,4-distannetane ring, which is a distorted rhombohedron containing distinct Sn–S [243.9(4), 243.5(4) pm] and Sn–O [204.2(8), 202.6(8) pm] bonds; the same reagents react under anaerobic conditions to yield the corresponding 1,3-dithia-2,4-distannetane
Na 2 S·9H 2 O与1,1,2,2-四(2,4,6-三异丙基苯基)-1,2-二溴莫丁汀在空气中的反应产生空间受阻的四元1-oxa-3 -thia-2,4-distannetane环,它是扭曲的菱面体,包含独特的Sn–S [243.9(4),243.5(4)pm]和Sn–O [204.2(8),202.6(8)pm]键;相同的试剂在厌氧条件下反应,生成相应的1,3-二硫代-2,4-二黄烷,这表明三元反应的1-硫杂-2,3-二香烷是这两个反应的共同中间体。
