Methylene sulfonate

As the (Eqs. 99,100) demonstrate, the secondary amides and amidines can be alkylated at the nitrogen 95148>. Push-pull amidines 58 can in certain cases be N-acylated with diphenylketene whereas methylene sulfone introduces a methylsulphonyl group u8). [Pg.114]

Various other routes have been reported to give the 1,4-benzothiazine ring, some of which are summarized below. Synthesis of the 1,4-benzothiazine 1,1-dioxides (105) from benzaldimine and methylene sulfone ylide has been reported.147... [Pg.165]

More recently new salts [(CF3S02)2CR]2C6H42-, (R = CO or SO2 [114], lithium pentafluoro sulfur difluoro methylene sulfonate LiS03CF2SF5 [115] and lithium bis(trifluoro methyl sulfonyl) methane, LiCH(S02CF3)2 [116] have been reported as plasticizing salts with PEO. While [(CF3S02)2CR]2C6H42 has been synthe-... [Pg.156]

Reaction of the stable a-monoanion with formaldehyde quantitatively eliminates triflate ion to create a-methylene sulfones (eq 5). Higher aldehydes did not react with the a-anion, but bromination is facile even at low temperature. [Pg.603]
