Abstract: Borates of certain etherdiamines are provided. These compounds give excellent results when tested in lubricants as friction reducing antioxidants or antirust additives.

Abstract: Dispersant lubricating oil additives are prepared by reacting oil-soluble dispersant compositions containing at least one primary or secondary amino group with SO.sub.2.

Abstract: Boron-containing heterocyclic compounds of the chemical formula: ##STR1## wherein at least one of R.sub.1, R.sub.2, R.sub.3, or R.sub.4 is an aryl, alkylaryl, or arylalkyl radical having from 1 to about 30 carbon atoms have been found useful as extreme pressure, anti-wear and friction-reducing additives for lubricating oils. The boron-containing heterocyclic compounds of the present invention are the reaction product of boric acid with the intermediate reaction product of a primary amine and an aromatic oxide. Metal derivatives of the boron-containing heterocyclic compounds are obtained by chemical reaction with a metal or compound thereof, particularly a first row transition metal or a Group IVA metal, or a compound thereof.

Abstract: Alkyl amines, alkyl diamines and borated adducts of alkyl amines and diamines are effective friction reducing additives when incorporated into lubricating oils.

Abstract: The use of amine boranes to inhibit the inflammation process is disclosed. These boranes, which are boron analogs of .alpha.-amino acids, effectively block the following: general inflammation, induced arthritis, and the writhing reflex associated with inflammation pain. The inflammation associated with pleurisy is also inhibited. The boron analogs are shown in vitro to inhibit the release of lysosomal enzymes from liver and polymorphonuclear neutrophils (PMNs). Further, prostaglandin synthesis is blocked by these compounds at a low concentration, viz, 10.sup.-6 M.Liver oxidative phosphorylation processes are also uncoupled by these compounds, but PMN migration is unaltered at 10.sup.-4 M. The elevation of cyclic adenosine monophosphate in PMNs correlates positively with in vivo antiarthritic activity. Studies in rodents demonstrate that these boron analogs may be used at safe therapeutic doses. Several compounds per se are included within the scope of the invention.

Abstract: The invention relates to alkylborane complexes with aromatic amines of the formula: ##STR1## in which R.sup.1 and R.sup.2 are the same or different (1-4C)-alkyl radicals, or together with the adjacent nitrogen atom are morpholino, piperidino or pyrrolidino radicals; R.sup.3 and R.sup.4 are independently selected from hydrogen, (1-4C)-alkyl, (1-4C)-alkoxy, di-(1-4C)-alkylamino, morpholino, piperidino and pyrrolidino; thexyl stands for 1,1,2-trimethylpropyl; and n is the integer 1 when R.sup.3 and R.sup.4 are other than nitrogen containing radicals, or the integer 1 or 2 when one of R.sup.3 and R.sup.4 is a nitrogen containing radical, or the integer 1, 2 or 3 when both R.sup.3 and R.sup.4 are nitrogen containing radicals.The complexes are more stable than thexylborane tetrahydrofuran complex, but are sufficiently reactive to be valuable as hydroborating and reducing agents.
