Nickel and cyclopropane reactions and photochemistry using matrix-isolation FTIR spectroscopy. Nickelacyclobutane synthesis and photofragmentation
The reactions between atomic nickel and cyclopropane in cryogenic matrices have been investigated. Atomic nickel was observed to insert spontaneously into a carbon-carbon bond of cyclopropane and form a four-membered unligated metallacycle, nickelacyclobutane. Visible photolysis induced metathesis of this metallacycle through Ni-C and C-C bond cleavages, resulting in a methylenenickel ethylene ..pi.. complex, CH/sub 2/Ni(C/sub 2/H/sub 4/). With UV irradiation this ..pi.. complex underwent activation of one of the C-H bonds of ethylene and rearranged to vinylnickel methyl, C/sub 2/H/sub 3/NiCH/sub 3/. C/sub 2/H/sub 3/NiCH/sub 3/ decomposed and released methane upon extended UV photolysis. Experimental results with cyclopropane-d/sub 6/ paralleled those of the undeuteriated system, except CD/sub 2/Ni(C/sub 2/D/sub 4/) was stable and underwent no further reactions or decomposition with UV irradiation.
