(V) with triorganotin hydrides, R3SnH (R = Me, n-Bu, Ph) gives the energetically unfavourable cis products, 2-triorganostannyl-1,2,3,4-tetrahydronaphthalene-1-car☐ylate (II), 1-triorganostannyl-1,2,3,4-tetrahydronaphthalene-2-car☐ylate (IV), and 3-triorganostannyl-1,2,3,4-tetrahydronaphthalene-2-car☐ylate (VI) in high yields, via a trans addition of the tin hydrides. The hydride abstractions by the intermediate
3,4-二氢萘-1-car☐酸酯(I),3,4-二氢萘-2-car☐酸酯(III)和1,4-二氢萘-2-car☐甲酯( V)和氢化三有机锡,R 3 SnH(R = Me,n-Bu,Ph)产生了在能量上不利的顺式产物,2-triorganostannyl-1,1,2,3,4-tetrahydronaphthalene-1-car☐ylate(II), 1-triorganostannyl-1,1,2,3,4-四氢萘-2-car☐ylate(IV)和3-triorganostannyl-1,1,2,3,4-四氢萘-2-car☐ylate(VI)通过反式添加氢化锡。中间体2-,1-,3-三有机锡烷基-1,2,3,4-四氢萘基(分别为XI,XII和XIII)氢化物的提取是立体定向的,并且仅从受阻较小的环侧进行。异构体II,IV和VI的结构是通过(a)将其转化为相应的氯二有机锡烷基衍生物VIII,I
