Paragraph 0063-0066, (2020/05/30)
The invention belongs to the technical field of fine chemicals and related chemistry, and provides an efficient preparation method of a 1-aryl-4-butene compound. The 1-aryl-4-butene compound can be obtained by taking halogen-containing methyl aromatic hyd

Alkylation of phthalonitrile radical anion sodium salt with terminal alkenyl bromides (4-bromobut-1-ene, 5-bromopent-1-ene, and 6-bromohex-1-ene) gave the corresponding 4-alkenylphthalonitriles which reacted with alkanethiols (BuSH and n-C10Hs

Using cyclopropylmethyl bromide as mechanism-sensitive reagent, it was shown that the reaction of phthalonitrile radical anion with alkyl halides in liquid ammonia involves electron transfer. The effects of the nature of alkyl bromide and counterion in th

The coupling of β-cyanocarbene complexes and 2-alkynylbenzoyl derivatives has been examined. The reaction afforded phenanthridine derivatives in a complex tandem process involving carbene-alkyne coupling, isobenzofuran formation, intramolecular Diels-Alder reaction using a nitrile dienophile, and deoxygenation. The chemistry could not be reproduced in non-chromium-based systems. Georg Thieme Verlag Stuttgart.

The selective fragmentation reactions of β-trimethylsilylketoximes have been proved to proceed effectively with acid catalysts giving the corresponding nitriles.Cyclic silylketoximes gave unsaturated nitriles.The fragmentation in the Beckmann rearrangement is completely controlled and directed by a trimethylsilyl group to lead the regio- and stereo-specific formation of the double bond.The catalytic fragmentation proceeds with the combination of trimethylsilyl ketoxime acetates and trimethylsilyl trifluoromethanesulfonate giving nitriles in high yields.Excellent stereospecificity of the fragmentation based on the stereochemical outcome was discussed.Simple stereo-controlled synthetic approach to some insect pheromones is also described.
