Abstract: Fractionable, reactor blend polypropylenes, directly obtainable from the polymerization reaction of propylene, having:(a) content of isotactic pentads (mmmm) comprised between 25 and 85%;(b) ratio M.sub.w,/M.sub.n <5;containing from 10 to 70% by weight of a fraction soluble in boiling diethyl ether, said fraction having a content of isotactic pentads (mmmm) comprised between 5 and 25%, and from 30 to 90% by weight of a boiling n-heptane-insoluble fraction, soluble in xylene at 135.degree. C., said fraction having a content of isotactic pentads (mmmm) comprised between 50 and 99%, are disclosed. These polymers are suitable as thermoplastic-elastomeric materials. A process for the preparation of these polymers and a process for the preparation of 2-aryl-substituted indenyl metallocene ligands is also disclosed.

Abstract: Disclosed is a process for the preparation of aryl-substituted propionic acid esters having the formula: ##STR1## wherein R and R.sup.1 are a C.sub.1 -C.sub.12 linear or branched alkyl, a C.sub.5 -C.sub.12 cycloalkyl, a C.sub.6 -C.sub.12 aryl or a C.sub.7 -C.sub.12 alkaryl or aralkyl, R.sup.2 is hydrogen or a C.sub.1 -C.sub.20 linear or branched alkyl and R.sup.3 is a C.sub.1 -C.sub.20 linear or branched alkyl, a C.sub.5 -C.sub.12 cycloalkyl, a C.sub.6 -C.sub.12 aryl or a C.sub.7 -C.sub.20 alkaryl or aralkyl, and may be the same or different, which comprises forming a reaction mixture of a phenol, at least one base catalyst and an acrylate, in the presence of a complexing agent effective in increasing the rate of reaction, wherein (i) substantially all of the side-product is removed from said reaction mixtrue prior to the addition of the complexing agent and (ii) all or substantially all of the acrylate is added at once to the reaction mixture.

Abstract: Indole and indole derivatives are prepared by contacting under mild reaction conditions an N-(2-toly)formidate, N-(3-methyl-2-pyridyl)formimidate, or N-methyldiazyl formimidate with an alkali metal amide.

Abstract: Phenyl isonitriles are prepared by reaction of substantially equimolar amounts on N-arylformimidates and a lithium dialkylamide.

Abstract: 2,6-dialkoxybenzoic acid is made by direct metalation of 1,3-dialkoxybenzene by potassium. The metalated dialkoxybenzene is carbonated and acidified to form the dialkoxybenzoic acid.
