<p>1368267 Di- and tri-olefinic compounds ZOECON CORP 29 Nov 1971 [1 Feb 1971 (5) 16 Feb 1971 8 Oct 1971] 55201/71 Heading C2C [Also in Divisions C5 and A5] Novel compounds of formula and intermediates of formula where n is 0 or 1, R<SP>1</SP>, R<SP>2</SP>, R<SP>4</SP> are C 1-6 alkyl, R<SP>3</SP>, R<SP>12</SP>, R<SP>13</SP> and R<SP>14</SP> are H or C 1-6 alkyl, Z is Br, Cl, F, or OR where R is H, carboxylic acyl, C 1-6 alkyl or cycloalkyl,Z<SP>1</SP> is H, Br, Cl, or F, Q is -COOR<SP>7</SP>,-COX, -COSR<SP>15</SP>, -COR<SP>15</SP> or -CONR<SP>8</SP>R<SP>9</SP>, R<SP>7</SP> is H, C 1-6 alkyl or C 4-8 cycloalkyl, R<SP>15</SP> is C 1-6 alkyl or cycloalkyl, R<SP>8</SP>, R<SP>9</SP> are H, C 1-6 alkyl C 1-6 alkenyl or cycolalkyl, and X is Br or Cl, are prepared in the B form by the methods described in 55200/71 from the corresponding unsaturated compounds. The preparation of precursor ketones and aldehydes of shorter chain length is also described as in 55200/71. The compounds in the A form are prepared (i) from the corresponding B compound by reaction with (a) hydrogen halide to give Z = halogen and Z<SP>1</SP> = H, (b) halogen to give Z and Z<SP>1</SP> = halogen, (c) mercuric acetate followed by reduction with NaBH 4 to give Z=OH and Z<SP>1</SP>=H, or (d) as in (c) but in the presence of alcohol to give the ether; or (ii) from the A compound in which Z = OH by reaction (a) with halide to give the ether, or (b) with acid, acid halide, or acid anhydride to give the acyl compound. Alternatively, Z and Z<SP>1</SP> may first be introduced into the carbonyl precursors, and the A compounds then be produced by the same methods as for the B compounds. The compounds are insecticides.</p> |
