C# Remove duplicated entries (but not keep first entries and second entries)

Is it possible to remove all non unique values in list structure? If List contains these values

11,9,8,7,6,5,4,10,8,7,6,5,4,2.

But after removing duplicates it should be

11,9,10,2.

If I try to divide this list on half and than apply List.Concat(List2).Disticnt() values 8,7,6,5,4 are still in the List.

var list = new List<int>() { 11, 9, 8, 7, 6, 5, 4, 10, 8, 7, 6, 5, 4, 2 };
var list2 = list.GroupBy(x => x)
                .Where(x => x.Count() == 1)
                .Select(x => x.First())
                .ToList();
