Hypervalent-iodine(iii) oxidation of hydrazones to diazo compounds and one-pot nickel(ii)-catalyzed cyclopropanation
Liu, Haixuan,Wei, Yunyang,Cai, Chun
, p. 674 - 678 (2016/01/12)
A one-pot process for the catalytic cyclopropanation of various alkenes with unsubstituted hydrazones is described. Iodosobenzene (Ph = O) was found to be a competent oxidant of hydrazones to diazo compounds. Ni(OH)2 was chosen as an effective and cheap metal catalyst. The cyclopropane products can be generated efficiently (5 min-4 h) in moderate to good yields (42-91%) under mild (80°C) and neat conditions.
Phenyl bridging in ring-substituted cumyloxyl radicals. a product and time-resolved kinetic study
Salamone, Michela,Bietti, Massimo,Calcagni, Alessandra,Gente, Giacomo
supporting information; experimental part, p. 2453 - 2456 (2009/10/24)
The reactivity of cumyloxyl radicals bearing cyclopropyl and 2,2-diphenylcyclopropyl groups in the para position has been investigated. Depending on radical structure, products deriving from C-C β-scission and/or cyclopropyl ring-opening are observed, sup
THE PHILICITY OF A TRIPLET CARBENE: ADDITIONS OF DIPHENYLCARBENE TO STYRENE SUBSTRATES
Tomioka, Hideo,Ohno, Kumiko,Izawa, Yasuji,Moss, Robert A.,Munjal, Ramesh C.

Triplet diphenylcarbene adds to ring-substituted styrenes as an ambiphile, reacting more rapidly with electron-rich or electron-poor styrenes than with styrene itself.
