    Effect of Marination on the Formation of Polycyclic Aromatic Hydrocarbons in Grilled Vegetables
    (Wiley, 2025) Kacmaz Ozcetin, Sibel; Artok, Levent
    The effect of marination on the formation of polycyclic aromatic hydrocarbons (PAH) in charcoal-grilled vegetables was studied. Various marinade ingredients, including apple cider vinegar, red grape vinegar, lemon juice, garlic powder, black pepper, and the food additive tert-butylhydroquinone (TBHQ) were applied to vegetable samples before charcoal grilling. The total phenolic content (TPC) and total antioxidant capacity (TAC) of each marinade ingredient were assessed for their contribution to PAH inhibition. A substantial decrease in PAH4 formation was observed in marinated vegetables. Red grape vinegar exhibited the strongest average inhibitory effect on total PAH4 formation (75%), followed by apple vinegar (68%), lemon juice (52%), garlic powder (34%), and black pepper (30%). Additionally, the TBHQ (67%) demonstrated a strong inhibitory effect, reducing total PAH4 formation by 67%. These findings offer valuable insights for reducing PAH levels in grilled vegetables and preventing their formation.

    Iron-Promoted 1,5-Substitution (sn2' Reactions of Enyne Acetates and Oxiranes With Grignard Reagents
    (Wiley, 2017) Taç, Doğan; Aytaç, İsmet Arınç; Karatavuk, Ali Osman; Kuş, Melih; Ziyanak, Fırat; Artok, Levent
    Acetate derivatives of 2-en-4-yne alcohols 1 and enyne oxiranes 4 regioselectively underwent 1,5-substitution (SN2′′) reactions with Grignard reagents in the presence of an iron compound to provide vinylallenes exclusively with the (E)-configuration. An alkali salt was needed to avoid the hydride-promoted reductive 1,5-substitution pathway for 1, whereas no such additive was needed for the effective conversion of 4 into the desired alkylated or arylated vinylallene structure.
