Reactions of cyclobutenones with nucleophilic reagents via vinylketen intermediates [PDF]
, 1976 While strong nucleophiles add to the endocyclic double bond of cyclobutenones to yield cyclobutanones, weaker nucleophiles (e.g. alcohols, aniline) interact with the vinylketens which are thermally or photochemically generated from cyclobutenones; the ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...
