Hydrocarbon activation. Synthesis of β-cycloalkyl (Di)nitriles through photosensitized conjugate radical addition

Photoinduced hydrogen abstraction from aliphatic cyclic hydrocarbons (C5 to C7, C12, as well as adamantane) by triplet aromatic ketones in the presence of α,β-unsaturated (di)nitriles offers a straightforward entry to the corresponding alkylated (di)nitriles via the alkyl radicals. Yields are moderate to good depending on the olefins structure (substitution in β slows down the addition to mononitriles, but with α,α-dinitriles electronic activation allows efficient alkylation also of β,β-disubstituted substrates). A tandem alkylation - cyclization process has been obtained with (1-methylpent-4-enylidene)malononitrile.
BIS(TRI-n-BUTYLSTANNYL)BENZOPINACOLATE: PREPARATION AND USE AS A MEDIATOR OF INTERMOLECULAR FREE RADICAL REACTIONS

Bis(tri-n-butylstannyl)benzopinacolinate (2) serves as a thermal source of tri-n-butylstannyl radicals and mediates intermolecular coupling of selected alkyl halides to O-benzylformaldoxime and electron deficient olefins.A free radical non-chain mechanism is proposed for these reactions.

Curran,Van Elburg
, p. 2861 - 2864 (2007/10/02)
Rate constants for the addition of alkyl radicals to allylstannanes lie in the range of 104-105 M-1 s-1 at 50-80°C.
