The reaction of the bis(methoxy)-2-pyridyl-phosphine (MeO)2P(2-py) with [Ni(MeCN)6](BF4)2 leads to the unexpected, single-step reduction of NiII and the formation of a tetrahedral nickel(0) complex.

Substituted 1

3-Cyclopropyl-5-(4-substituted)-1-phenyl-4,5-dihydro-1H-pyrazoles derived from corresponding chalcones were synthesized and evaluated for their biological activities. A convenient synthesis of a library of these compounds in 1-butyl-3-methylimidazolium hexafluorophosphate-water biphasic system at ambient temperature has been accomplished. The ionic liquid, [bmim][PF6] and water which are immiscible, has been easily recycled and reused after separation of the products without any noticeable diminution in its activity.

High Yields

Homoallylic and homopropargylic alcohols undergo smooth coupling with ketones in the presence of molecular iodine at ambient temperature to produce spirocyclic-4-iodotetrahydropyrans and 5,6-dihydro-2H-pyrans, respectively, in high yields in a short reaction time with high selectivity. The use of molecular iodine makes this procedure quite simple, more convenient, and cost-effective.Key words: Prins-cyclization, iodine, homopropargylic alcohol, spirocyclic-4-iodopyrans.
