It's impossible to tell how your Button is handling disabled under the hood but assuming it´s working like the JSX element .

First, JSX elements are just functions that takes a set of arguments (props). So you still need to give it a disabled:boolean. As you can see below you need to provide a name and a value. Your attempt at {this.state.d} gives just the value true/false. Please look at the snippet below for how you can do it. Either explicit or by giving it a named variable or finally by spreading out an object.

class HelloWorldComponent extends React.Component {
  constructor(){
    super();
    this.state = {
      disabled: true
    }
  }
  render() {
  const disabled = this.state.disabled; //Pull out the value to a named variable
    return (  
    <div>
      <button disabled={false}>Button1</button> 
      <button disabled>Button2</button> 
      <button {...this.state}>Button3</button>  
    </div>
    );
  }
}

React.render(
  <HelloWorldComponent/>,
  document.getElementById('react_example')
);
