The present invention discloses a catalytic system for preparing highly branched alkane from olefin, which contains novel nickel or palladium complexes. In the presence of the catalytic system, highly branched oily alkane mixture can be efficiently obtained from olefins (such as ethylene) under mild conditions. The alkane mixture has a low bromine number, and can be used as a processing aid(s) and lubricant base oil with high-performance. Provides also was a method for preparing the catalyst and a method for preparing an oily olefin polymer.

A method of conversion of thioimidates into amidines includes reacting a starting material compound including a thioimidate with a nitrogen-containing reagent to form a product compound including an amidine in place of the thioimidate in the starting material compound. The nitrogen-containing reagent includes a primary amine, a secondary amine, an ammonium salt, or a combination thereof. The thioimidate includes SR.sup.1, wherein R.sup.1 is substituted or unsubstituted (C.sub.1-C.sub.20)hydrocarbyl. A method of forming a cyclized product includes intramolecularly reacting an amidine with a carbonyl carbon to form the cyclized product including a 4H-imidazolone and/or a derivative thereof.
