A new synthetic route for obtaining polyfunctional nitrile N-oxides from OH-tethering nitrile N-oxide is reported. OH-Tethering nitrile N-oxide is synthesized using the proposed route by using an intermediary nitroalkane and derived to polyfunctional ones via OH-involving condensations. The polyfunctional nitrile N-oxides undergo a catalyst-free crosslinking reaction to form crosslinked natural rubber (NR). The physical properties of the crosslinked NR indicate the occurrence of effective crosslinking. A crosslinker with ester-connected two nitrile N-oxide functions is demonstrated to have favorable decrosslinking ability.

到新的合成路线OH官能化的腈Ñ氧化物和多官能团的腈Ñ用于点击交联和天然橡胶的解交联-oxides †

用于获得多官能腈的新合成路线ñ从OH-栓系腈-oxides Ñ氧化物报道。使用中间硝基链烷烃，使用建议的路线合成OH拴合腈N-氧化物，并通过涉及OH的缩合反应生成多官能团。多官能腈N-氧化物经过无催化剂的交联反应以形成交联的天然橡胶（NR）。交联的NR的物理性质表明有效交联的发生。已证明具有酯连接的两个腈N-氧化物功能的交联剂具有良好的去交联能力。
