Abstract
2-(4-R)-oxazolinyl-o-carboranes (R = i-propyl 1, t-butyl 2 CabOxa)를 포함하는 카이랄 유기주석 할로겐화물 시리즈는 카이랄 oxazoline에 유용한 o-carborane에서 얻어졌다. 카이랄 유기주석 할로겐화물을 대표하는 [2-(4-i-propyl)-oxazolinyl-o-carboranyl]SnMe2Br (4) X-ray 구조분석은 N→Sn 상호작용으로 인해 안정한 5-배위 주석 중심 구조를 나타낸다. 이와 유사한 분자 내 5-배위 주석화합물을 장려하는 O→Sn은 methoxy-o-carborane ligands, MeOCH(Z)-o-carborane (Z = H 7, Ph 8 CabOMe)로부터 얻어진다. 단단한 o-carboranyl backbone 은 유기주석 화합물로부터 손쉬운 구조물을 얻기 위한 기본 골격으로 공급된다.|A series of chiral organotin halides containing 2-(4-R)-oxazolinyl-o-carboranes(R = i-propyl 1, t-butyl 2; Caboxa)was prepared from o-carborane with a chiral oxazoline auxiliary. X-ray structural analysis of the representative chiral organotin halide, [2-(4-i-propyl)-oxazolinyl-o-carboranyl]SnMe2Br (4), revealed the formation of a stable penta-coordinated tin center due to a N→Sn interaction. Similar O→Sn assisted intramolecular penta-coordinated tin complexes (9 and 10) were prepared from methoxy-o-carborane ligands, MeOCH(Z)-o-carborane(Z = H 7, Ph 8; CabOMe), respectively, and a rigid o-carboranyl backbone provided the basic skeleton for the facile formation of organotin complexes.
