Thank you for writing.
This property of Black Walnuts is well known. https://mortonarb.org/plant-and-protect/tree-plant-care/plant-care-resources/black-walnut-toxicity/
It helps the Walnut compete. https://gardenprofessors.com/allelopathy-helps-black-walnuts-compete/
Ironically, buckthorn also suppresses competitors by means of a different chemical.
