摘要:Microfluidic device for the synthesis of micro and nanoproducts and manufacturing method of said microfluidic device. The microfluidic device comprises a top piece made of photopoly- merizable resin, which in turn comprises at least two inlet holes and at least one outlet hole; one or more bottom pieces made of photopolymerizable resin, which in turn comprise microchannels; and fastening means between the top piece and the bottom piece or bottom pieces. The manu- facturing method comprises a step of modeling the pieces of the microfluidic device; a 3D printing stage of the pieces of the microfluidic device; a post-processing stage of the pieces of the microfluidic device; and a stage of assembling of the microfluidic device.

摘要:An improved regiospecific synthesis of organic phosphonous acids, comprising of hydrophosphorylation of an olefin with hydrophosphorous acid in the presence of an inorganic persulfate, which acts as a source of free radicals at a pH ranging from 4.5 to 7.0, in which the orientation of addition is anti-Markonikoff. The process enables production of organic phosphonous acids at lower temperature and atmospheric pressure under milder pH conditions for better regioselectivity in hydrophosphorylation and obtain the phosphonous acid with good yield and purity following simple isolation procedure. Phosphonous acids obtained by the process are commercially valuable as effective detergents and wetting agents, lubricants and lubricant additives, plasticizers for plastics and resins, corrosion inhibitors, chemicals including insecticides and pesticides, cobalt extractants and as key intermediates for preparation of commercially important angiotensin converting enzyme (ACE) inhibitors.

摘要:The invention relates to solid phase processes for the systematic preparation of chemical compounds from the group of the phosphonous or phosphinic acids and/or derivatives thereof and the corresponding substance libraries which can be employed for test purposes, in particular tests for biological activity. The compounds n YR 1 P(â•?O)(OR 3 )R 2   (I) n in which Y, R 1 , R 2 , R 3 are as defined in claim 1 are prepared by reacting a resin-linker adduct (II) n [resin polymer]-[linker-Z-E 1 -S 1 ] n n in the presence of a suitable Pd catalyst with a phosphinate (III) n A 1 -O—(PHO)A â–¡   (III) n with substitution of the group S 1 to give the compound (IV) n [resin polymer]-[linker-Z-E 1 -P(H)(â•?O)—OA 1   (IV) n and cleaving the compound (I) after derivatization reactions on the resin from the resin-linker adduct. n The invention also provides the intermediate steps and resin-linked intermediate compounds and also the substance libraries obtained.
