A heterophasic polymer composition comprises a propylene polymer phase, an ethylene polymer phase, and a compatibilizing agent. The compatibilizing agent comprises (i) an acyclic carbon-carbon double bond having a first carbon atom and a second carbon atom, (ii) an electron withdrawing group directly bonded to the first carbon atom in the acyclic carbon-carbon double bond, and (iii) a second carbon-carbon multiple bond in conjugation with the acyclic carbon-carbon double bond, wherein the second carbon-carbon multiple bond is linked to the acyclic carbon-carbon double bond through the second carbon atom.

A procedure for the Cu-catalyzed hydrocyanation of α-aryl diazoesters has been developed using acetone cyanohydrin as a source of hydrogencyanide (HCN). It was found that the addition of trimethylsilyl cyanide (TMSCN) significantly accelerates the conversion presumably by delivering free cyanide ion in situ, thus producing various types of α-aryl cyanoacetates in high yields under mild conditions
