Reaction of silyl thioketones with lithium diethylphosphite : First observation of thia-brook rearrangement Takeda, Kei Sumi, Koichi Hagisawa, Susumu Inter-element linkage Silyl thioketone Thia-Brook rearrangement Sulfur-phosphorus bond sulfur-silicon bond 430 Reaction of silyl thioketone 7 with lithium diethylphosphite at –98 °C afforded an S-attack product 8 and a formal C-attack products 10 and 11, which were formed by S-to-C migration of the phosphoryl group in 8 followed by C-to-S migration of the silyl group (thia-Brook rearrangemnet), in a ratio depending on the conditions. The relative facility of the thia-Brook rearrangement was compared with that of the Brook rearrangement using the (t-butyldimethylsilyl) diphenylmethyl derivatives 22 and 23. http://purl.org/coar/resource_type/c_6501 Elsevier Science 2000-10-06 AO 0022-328X 449 Journal of organometallic chemistry 1-2 611 454 449 Journal of organometallic chemistry https://hiroshima.repo.nii.ac.jp/records/2007468 eng http://dx.doi.org/10.1016/S0022-328X(00)00482-4 open access Copyright (c) 2000 Elsevier Science S.A.
