  Synthesis of peri-Cyclobutarenes by Thermolysis of [Methoxy(trimethylsilyl)methyl]arenes

  摘要：

  [Methoxy(trimethylsilyl)methyl]arenes are readily prepared by reactions of chlorotrimethylsilane with (alpha-methoxy)arenylmethyllithium reagents as obtained from (methoxymethyl)arenes and t-BuLi. The [methoxy(trimethylsilyl)methyl] arenes eliminate methoxytrimethylsilane at 525-675 degrees C/0.05-0.10 mm to yield peri-cyclobutarenes as derived from arenylcarbenes. Of importance is the fact that the initial arenylcarbenes generated insert into adjacent peri C-H bonds and/or isomerize to other arenylcarbenes that insert into their peri C-H bonds to give peri-cyclobutarenes. Thus, flash-vacuum pyrolysis of 1-[methoxy(trimethylsilyl)methyl]naphthalene (13) at 575-675 degrees C/0.05-0.10 mm yields 1H-cyclobuta[de]naphthalene (6, up to 39%) in practical quantities. 2-[Methoxy(trimethylsilyl)methyl]naphthalene (23) also affords 6 as a major thermolysis product. At 510 degrees C/ 0.05-0.10 mm 4-methoxy-1-[methoxy(trimethylsilyl)methyl]naphthalene (29) decomposes to 4-methoxy-1H-cyclobuta[de]naphthalene (31, 46%). Under similar conditions, 2-methoxy-1-[methoxy(trimethylsilyl)methyl]naphthalene (33) converts to 1,2-dihyrdronaphtho[2,1-b]furan (35, 64%) and naphtho[2,1-b]furan (36, 31%), presumably by insertion of 2-methoxy-1-naphthylcarbene (34) into a C-H bond of its o-methoxy group and then dehydrogenation of the resultant dihydrofuran. Further, 1-[methoxy(trimethylsilyl)methyl]-6-methylnaphthalene (39) pyrolyzes (510 degrees C/0.10-0.20 mm) to 6-methyl-1-naphthylcarbene (40), which isomerizes in part to 7-methyl-1-naphthylcarbene (49); carbenes 40 and 49 then undergo peri C-H insertion to give 3-methyl-1H-cyclobuta[de]naphthalene (41) and 2-methyl-1H-cyclobuta[de]naphthalene (42) in an 8:1 ratio and a combined yield of 44%. The pyrolytic method is particularly valuable for preparing higher peri single carbon atom bridged arenes such as 4H-cyclobuta[jk]phenanthrene (53, 65%) and 3H-cyclobuta[cd]pyrene (59, 86%).

  This invention provides acrylate polymers having at least two different ester groups. The ester groups are selected from the following: a) an aralkyl group; b) a linear alkylether group; c) a polyethoxylated alkylaryl group; and d) a polyethoxylated alkyl group, with the proviso that at least one of said ester groups is selected from b) or d). Processes for preparing such polymers and processes for breaking emulsions with these acrylate polymers are also provided.
